What is the approx exit number range, grouped in intervals 10, of a freeway through a city center? And how many ranges can we cover with cities with a population of at least 100k before we get to one that have no examples? If the downtown exits covers 2 ranges (like exits 19-22), pick the one that have more exits in the city center.
I'll start off the list with some cities I know of:
0-9:
Too many to list

10-19: I-35W in Minneapolis

190-199: I-96 in Detroit
200-209: I-75 in Toledo
20-29: I-290 Chicago
Theoretical numbering, should I-88 ever trump/replace I-290 east of Hillside, IL:
150-159: What I-88 would be in Chicago, if it were designated on the Ike instead of 290
150's - I-10 Baton Rouge
200's - I-49 Shreveport
230's - I-10 New Orleans
iPhone
140-150 I-25 Colorado Springs
270-279 I-70 Denver
I-64 can really go from Exit 250 to Exit 299 for Hampton Roads.
But to simplify it...
250-259 - I-64 Newport News
260-269 - I-64 Hampton
270-279 - I-64 Norfolk
280-289 - I-64 Virginia Beach (in reality, it's Norfolk-Virginia Beach-Chesapeake)
290-299 - I-64 Chesapeake
I-10 in Beaumont, TX: 850-859
I-5:
1-9 Vancouver
10-19 San Diego
25-34 Medford*
100-109 Olympia
120-129 Roseburg
130-139 Los Angeles, Tacoma
140-149 Burbank
160-169 Seattle
190-199 Eugene/Springfield, Everett
250-259 Salem, Bellingham
300-309 Portland
470-479 Stockton
510-519 Sacramento
670-679 Redding
*Medford's only two exits are 27 and 30, with the city center roughly equidistant from both exits. It's also on the low end for population, around 84k.
This thread is no fair to states that still use sequential exits - but it's really more like justice than injustice. Take note, NYSDOT.

I couldn't find any city center with exits in the 90-99 range

Too bad I-70 ends in a parking lot at Exit 94 in Baltimore! :popcorn:
This took way too long to find one... I-55 Exits 90-99 serve Jackson, MS.
I also think OP can include that I-85 serves Atlanta with the 80-89 range. The thing is, part of that is concurrent with I-75 and it's I-75's numbers that are posted.
For 120-129 there's I-85 Greensboro NC.

I don't mind noting theoretical exit numbers for routes that been put in the backseat for exit numbers in a concurrency. Another one is I-90 in Chicago, which is in its MM 90-99 range passing by the loop. If the 90/94 concurrency used I-90's exit numbers (which it really should have as I-90 have the larger exit numbers set in IL, and I-94 doesn't get to the 80s-90s range in its own exit numbers), the exit 51 set would be exit 92 instead.
I-94 in Milwaukee fully covers both 300-309 and 310-319. I know that situation was laid out in the OP, but this case really can't be split off.
I-90 Madison: 130-139

I've never been there, but is Milwaukee's downtown really that large? Normally, downtowns only cover up to 3-4 miles on a freeway, not 20.
Adding another one in WI, 260-269 for US 12 in Madison.

It's not, they seem to be using the entire city limit and not just the downtown.
The I-94 interchange with I-43 and I-794 is in the range 310-319.
Seems like the lowest not covered so far is 180-189, and I haven't found one myself yet. Next highest is 330-339.
Some for the higher ranges not covered that I found an example:
280-289: I-90 Spokane
420-429: I-70 KCK
450-459: I-80 Omaha
Since I just mentioned "freeway" in the op, freeways in other countries could also be used. Like the Gardiner could count for 150-159 and ON 401 for 360-369 in Toronto.
Would I-96 in Detroit count for 180-189?
1-10 NH 48 Gugaram, Haryana, India (so far, the only Indian highway I've seen with multiple or non-sequential[?] exit numbers on OSM)
50-59 I-84/US 30 Boise (between I-184 and US 20/26)
250-259 AB 2 Calgary
370-379 BC 1->3->5* Kamloops
380-389 AB 16 Edmonton
Difficult to find a viable option for Vancouver BC, Medicine Hat, Regina, Saskatoon, or Winnipeg.
*Exit numbers start on BC 1, transfer to BC 3 in Hope, then immediately to BC 5 along the Coquihalla Highway, then back to BC 1 past Kamloops, while BC 1 itself takes a longer route along the Fraser River. Also, BC 97 has the long wrong-way concurrency with BC 1 east and west of Kamloops.

I counted I-96 Detroit for 190-199.

So close, but I-24 in Chattanooga's main downtown exit is 179.

Looks like I got one for 180-189: I-64 in Richmond.

Utah's metropolitan area urban centers, which cover many of the higher ranges:
0-9: I-15 St George
81-89: I-84 Ogden
120-129: I-80 Salt Lake City
260-269: I-15 Provo
300-309: I-15 Salt Lake City
340-349: I-15 Ogden

Wow! Richmond exits run from Exit 178 (Short Pump) to Exit 200 (I-295), possibly including Exit 205 (Bottoms Bridge) which I frequently used as to access Richmond when I worked in Fulton Yards on that side of town.
Durham exits just barely get into this range from Exit 170 (US-70) to Exit 182 (Red Mill Road).
For just the center of the city, as in downtown? Or the area around it?
Houston: interstate 10: 760-770
