(D) Let us analyze the differences between consecutive terms:$289 - 225 = 64 = 8^{2}$$374 - 289 = 85$$397 - 374 = 23$$415 - 397 = 18$$424 - 415 = 9 = 3^{2}$Let us re-examine the pattern by adding squares of decreasing numbers:$225 + 8^{2} = 225 + 64 = 289$$289 + 7^{2} = 289 + 49 = 338$$338 + 6^{2} = 338 + 36 = 374$$374 + 5^{2} = 374 + 25 = 399$$399 + 4^{2} = 399 + 16 = 415$$415 + 3^{2} = 415 + 9 = 424$Comparing this with the given series $(225, 289, 374, 397, 415, 424)$,we see that $397$ is incorrect as it should be $399$.

$101$	$323$	$545$	$767$	$989$	$111011$
$34$	$(A)$	$(B)$	$(C)$	$(D)$	$(E)$

In the following number series,one of the numbers does not fit into the series. Mark the wrong number in the series.
$225 \quad 289 \quad 374 \quad 397 \quad 415 \quad 424$
