Question

Find the missing number in the following series. 5, 8, 13, 21, 34, 55, (…), 144, 233

• A. 94
• B. 91
• C. 89
• D. 85

Answer 1

Answer:

C. 89

The missing number in the series is 89.

This is a standard Fibonacci sequence pattern, where each number is found by adding up the two numbers before it:

• 5 + 8 = 13

• 8 + 13 = 21

• 13 + 21 = 34

• 21 + 34 = 55

• 34 + 55 = 89 (Missing Number)

• 55 + 89 = 144

• 89 + 144 = 233
