Select the number that can replace the question mark (?) in the following series.

6, 12, 60, 222, 606, ?

1. 1458
2. 1768
3. 1356
4. 1969

Answer 1

Correct Answer - Option 3 : 1356

Given series: 6, 12, 60, 222, 606, ?

6 + 6 = 12

12 + 48 = 60

60 + 162 = 222

222 + 384 = 606

606 + 750 = 1356

The added numbers follow a certain pattern, which is as follows:

6 → 6 × (1)3 = 6

6 → 6 × (2)³ = 48

6 → 6 × (3)3 = 162

6 → 6 × (4)3 = 384

6 → 6 × (5)3 = 750

Hence, 1356 is correct.
