Question

225, 196, 169, 144, 121, 80,.....

Find the wrong term of above series.

• A. 80
• B. 121
• C. 169
• D. 196
• E. 144

Answer 1

The correct option is A 80

By taking a close look at all the numbers in the sequence it is clear that all the given numbers are perfect squares of numbers.

$15\times 15=225$

$14\times 14=196$

$13\times 13=169$

$12\times 12=144$

$9\times 9=81$ but the number given in the series is 80

So 80 is the wrong term from the series.

Option A is the correct answer.
