Question

The given number tower follows a pattern.
Identify the pattern and find the missing number in the pattern.

• A. 6
• B. 7
• C. 8
• D. 9

Answer 1

The correct option is C 8

For the first step, we can observe the following: 1 + 2 = 3

For the second step, we observe the following: 2 + 3 = 5


So, the number on the top floor of the tower is the sum of the two numbers of the floor just below it.

∴ In the third step, the number on the top floor will be: 3 + 5 = 8
