CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. 36 is 626^2, and 6 is one more than 5: add 1, then square.

  2. For 6: (6+1)2=72=49(6 + 1)^2 = 7^2 = 49.

Worth noting

36 squares 6 itself, forgetting the '+ 1'. 35 and 50 are 62−16^2 - 1 and 72+17^2 + 1: the pattern is an exact square, with nothing added or subtracted.
