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: A
Explanation
1) 14: 24
(Both numbers are 1 less than the squares of
consecutive numbers: 4 and 5)
14 = 42 - 2 (or 3.872 – 1; this is not an exact square
pattern)
24 = 52 – 1
2) 35:48
35 = 62 - 1
48 = 72 - 1
(Both numbers are 1 less than the squares of
consecutive numbers: 6 and 7)
3) 63:80
63 = 82 - 1
80 = 92 - 1
(Both numbers are 1 less than the squares of
consecutive numbers: 8 and 9)
4) 15:24
15 = 42 - 1
24 = 52 – 1
Option 1 is different.
Here, the first number does not follow the (n2 - 1)
pattern.
