Question

Find out the wrong term in the given series:

$143,156,169,182,221,232,274$

• A. $182$
• B. $274$
• C. $232$
• D. $221$

Answer 1

Answer: (C)

$232$

There are two series.
First is $143,169,221,247$
$143+26=169$
$169+52=221$
$221+26=247$
Second is $156,182,234$
$156+26=184$
$182+52=234$
Thus the complete series is $143,156,169,182,221,234,247$
So the wrong term is 232.
Hence, option 'C' is correct.
