Question

Study the given pattern carefully and select the number that can replace the question mark (?) in it.

6	12	21
19	49	85
3	4	?

1. 9
2. 7
3. 4
4. 6

Answer 1

Correct Answer - Option 3 : 4

The given matrix:

6	12	21
19	49	85
3	4	?

The logic is as follows:
Column 1: 6 × 3 + 1 = 19
Column 2: 12 × 4 + 1 = 49
Similarly,
Column 3: 21 × 4 + 1 = 85

Hence, '4' will replace the question mark in the given matrix.
