Select the set of numbers that is not similar to the following set: (13, 64, 90)
Show answer & explanation
Correct answer: A
Explanation
For the given set (13, 64, 90):
- 2nd Number: (1st Number × 5) − 1 → (13 × 5) − 1 = 64
- 3rd Number: (1st Number × 7) − 1 → (13 × 7) − 1 = 90
Checking the Options:
Option 2: (9, 44, 62)
- 9 × 5 − 1 = 44
- 9 × 7 − 1 = 62 (Follows pattern)
Option 4: (12, 59, 83)
- 12 × 5 − 1 = 59
- 12 × 7 − 1 = 83 (Follows pattern)
Option 1: (8, 38, 55)
- 8 × 5 − 1 = 39 ≠ 38 (Does not follow pattern)
Therefore, Option 1 is the set that is not similar to (13, 64, 90).
