Question

Which number replaces the question mark?
4, 9, 16, 25, ?, 49

• A. 40
• B. 36
• C. 32
• D. 30

Hint:

When identifying patterns in number sequences, check if the numbers are squares, cubes, or follow other standard mathematical progressions.

Answer 1

The Correct Option is B

The given sequence is: \[ 4, 9, 16, 25, ?, 49 \] Observe that these numbers are squares of consecutive integers: \[ 4 = 2^2, 9 = 3^2, 16 = 4^2, 25 = 5^2, 49 = 7^2 \] The missing number is the square of 6: \[ 6^2 = 36 \] Thus, the number that replaces the question mark is \( \boxed{36} \).
