Instructions
Each of the following questions has a series of numbers which follow a definite pattern except for one number. Identify the incorrect term of the series.
Solution
$$ 2^3 - 2^2 $$ = 4
$$ 3^3 - 3^2 $$ = 18
$$ 4^3 - 4^2 $$ = 48
$$ 5^3 - 5^2 $$ = 100
$$ 6^3 - 6^2 $$ = 180
$$ 7^3 - 7^2 $$ = 294
As we can see, 295 is the incorrect term in the given series. Therefore, option B is the correct choice.
