| 7 | 3 | 10 |
| 3 | 4 | 7 |

Correct Answer: 2
Solution : Given:
| 7 | 3 | 10 |
| 3 | 4 | 7 |
| 2 | 7 | ? |
| 42 | 84 | 140 |
The pattern can be observed running vertically down in the columns.
Column 1:
7 × 3 × 2 = 42
Column 2:
3 × 4 × 7 = 84
Column 3:
10 × 7 × (?) = 140
⇒ 70 × (?) = 140
⇒ (?) = 140 ÷ 70
⇒ (?) = 2
So, 2 is the missing term in the series. Hence, the first option is correct.
