In three of the following pairs are same by same pattern except one pair. Which pair does not follow this pattern?
Show answer & explanation
Correct answer: D
Explanation
Each pair consists of consecutive perfect squares except option (4),
9 = 32, 16 = 42
16 = 42, 25 = 52
25 = 52, 36= 62
36= 62, 64= 82 not consecutive perfect squares. (Missing 49 = 72)
Option (4) is the correct answer.
