Question

Identify the fifth number in the series: 122, 144, 166, 188, ?

• A. 234
• B. 210
• C. 345
• D. 310

Hint:

For number series questions, the first step is always to find the difference between consecutive terms. If the difference is constant, it's an arithmetic progression. If not, look for a pattern in the differences themselves.

Answer 1

The Correct Option is B

Let's analyze the differences between consecutive terms in the series. \[ 144 - 122 = 22 \] \[ 166 - 144 = 22 \] \[ 188 - 166 = 22 \] The series is an arithmetic progression with a common difference of 22. To find the next term (the fifth term), we simply add 22 to the fourth term. \[ \text{Fifth term} = 188 + 22 = 210 \] The fifth number in the series is 210.
