12, 72, 360, 1440, 4320, 8640, 8600

1. 8600
2. 8640
3. 12
4. 72
5. 360

Answer 1

Correct Answer - Option 1 : 8600

Given:

12, 72, 360, 1440, 4320, 8640, 8600

Calculation:

The logic that follows here is:

12 × 6 = 72

72 × 5 = 360

360 × 4 = 1440

1440 × 3 = 4320

4320 × 2 = 8640

8640 × 1 = 8640 ≠ 8600

There should be 8640 instead of 8600.

∴ 8600 is the wrong term.
