Question

DIRECTIONS for the question: In the following question, one term in the number series is wrong. Find out the wrong term.
196, 169, 144, 121, 101

• A. 101
• B. 121
• C. 169
• D. 196
• E. 144

Hint:

In wrong term series: • Memorize perfect squares up to 30 and perfect cubes up to 15. This allows for instant recognition of patterns.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Identify the mathematical relationship shared by the majority of the numbers in the series.
Step 2: Detailed Explanation:
$196 = 14^2$
$169 = 13^2$
$144 = 12^2$
$121 = 11^2$
Step 3: Calculation:
The sequence consists of squares of descending integers. The next term should be $10^2 = 100$. The series given ends in 101.
Step 4: Final Answer:
The wrong term is 101. Thus, the correct option is (a).
