One possible answer could be that the incorrect number is 1134 and the correct number is 1132.
Instead of 28, it should be 30(5^2 + 5) to maintain the pattern.
On calculating the differences between consecutive terms:
- 1200 - 1194 = 6 (2^2 + 2)
- 1194 - 1182 = 12 (3^2 + 3)
- 1182 - 1162 = 20 (4^2 + 4)
- 1162 - 1134 = 28 ( Should be 30 = 5^2 + 5)
- 1134 - 1090 = 44 (If the previous number is 1132; diff = 42 and which is 6^2 + 6)
- 1090 - 1034 = 56 (7^2 + 7)

What was your IITJEE rank?
If not IITJEE, share your rank or percentage from any major exam or competition..
Personally, I sucked at IITJEE and my rank was 112,700. I am ashamed to talk about this to anyone normally but here I can share it.
