Number series – find the wrong term (identify the outlier). Sequence: 56, 72, 90, 110, 132, 150

Introduction / Context:
This is a difference-pattern series where each step increases by a steadily growing even number. One term breaks the pattern and must be identified.

Given Data / Assumptions:

• Series: 56, 72, 90, 110, 132, 150
• One term is incorrect.

Concept / Approach:
Compute successive differences and check whether they follow a simple progression, such as adding even numbers that increase by 2 each time.

Step-by-Step Solution:

Verification / Alternative check:
Replace 150 with 156 to obtain differences 16, 18, 20, 22, 24, a consistent arithmetic progression of even numbers.

Why Other Options Are Wrong:

• 72, 110, 132: Each fits perfectly into the growing-difference pattern.

Common Pitfalls:
Looking at ratios when the structure is additive. Always test both methods, but here differences immediately reveal the rule.

Final Answer:
150
