Select the number from among the given options that can replace the question mark (?) in the following series.
6, 24, 60, 120, 210, ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 336.
The logic used here is:
6 + (6 × 3) = 24
24 + (9 × 4) = 60
60 + (12 × 5) = 120
120 + (15 × 6) = 210
210 + (18 × 7) = 336
