Select the option in which the numbers are related in the same way as are the numbers of the following set.
(12, 30, 61)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. (18, 45, 91).
The logic used here is:
(12, 30, 61)
12 × 2 = 24
12 ÷ 2 = 6
24 + 6 = 30
30 × 2 + 1 = 61
Similarly;
(18, 45, 91)
18 × 2 = 36
18 ÷ 2 = 9
36 + 9 = 45
45 × 2 + 1 = 91
Hence, the correct answer is (18, 45, 91).
