3, 3, 12, 108, 1728, 43300

1. 1728
2. 43300
3. 108
4. 3
5. 12

Answer 1

Correct Answer - Option 2 : 43300

Given:

3, 3, 12, 108, 1728, ?

Calculation:

The logic follows here is:

3 × 1² = 3 × 1 = 3

3 × 2² = 3 × 4 = 12

12 × 3² = 12 × 9 = 108

108 × 4² = 108 × 16 = 1728

1728 × 5² = 43200 ≠ 43300

There should be 43200 instead of 43300.

∴ 43300 is the wrong term.
