164285

I investigated adding the first number to the last number on each side of the street. Eg 1+29, 3 + 27, 5+ 25 and so on. A pattern I noticed was that these pairs always added up to 30. However 15 doesn't have pair but if I double the number it will add up to 30.

I did the same with the opposite side of the street, the even numbers. So I added 2+30, 4+ 28, 6 + 26 and so on. A pattern I noticed was that these pairs always added up to 32. However this time 16 doesn't have a pair but if I double it the answer will also be 32.
