Select the option in which the numbers are related in the same way as the numbers of the following set.
(7, 12, 18)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (8, 14, 21).
(7, 12, 18) → 7 + (7 - 2) = 7 + 5 = 12; 12 + (7 - 1) = 12 + 6 = 18
(8, 14, 21) → 8 + (8 - 2) = 8 + 6 = 14; 14 + (8 - 1) = 14 + 7 = 21
