correct answer is: option b (b)[180]
Explanation:

Study the given pattern carefully and select the number that can replace the question mark (?) in it. The pattern is: 14 4 28, 21 6 63, 45 8 ?

Options: a: 195, b: 180, c: 210, d: 150

Explanation:

Let's analyze the pattern step by step.

First Triplet: 14, 4, 28

\(14 \times 4 = 56\)

\(56 \div 2 = 28\)

Second Triplet: 21, 6, 63

\(21 \times 6 = 126\)

\(126 \div 2 = 63\)

Third Triplet: 45, 8, ?

\(45 \times 8 = 360\)

\(360 \div 2 = 180\)

Therefore, the number that can replace the question mark (?) is 180.

Final Answer: \(\boxed{180}\)
