What will come in place of the question mark (?) in the following number series? 34, 55, 89, 144, 233, ?

Show answer & explanation

Correct answer: C

Explanation

Given series: 34, 55, 89, 144, 233, ?

We notice that:

34

34 + 55 = 89

55 + 89 = 144

89 + 144 = 233

This is following the Fibonacci-like pattern where each term is the sum of the previous two terms.

The Missing Term:

Using the pattern: 233 + 144 = 377

Hence, the correct answer is option (3).
