Concept:

The pattern is that the second number equals twice the square of the first number:

2 \times (\text{first})^2

Explanation:

Check each option using this rule:

For 4:

2 \times 4^2 = 2 \times 16 = 32

– matches.

For 6:

2 \times 6^2 = 2 \times 36 = 72

– matches.

For 8:

2 \times 8^2 = 2 \times 64 = 128

– given is 126, so does not match.

For 10:

2 \times 10^2 = 2 \times 100 = 200

– matches.

Only option 3 deviates from the pattern.
