Vedclass · Answer

(A) The sequence can be split into two alternating series based on their positions:Series $1$ (odd positions): $455, 465, 485, 475$Series $2$ (even positions): $445, 435, 415$Analyzing the differences in Series $1$:$465 - 455 = 10$$485 - 465 = 20$$475 - 485 = -10$Analyzing the differences in Series $2$:$435 - 445 = -10$$415 - 435 = -20$In Series $1$,the pattern of differences should be $+10, +20, +30$. Therefore,the term $475$ is incorrect because $485 + 30 = 515$. Thus,$475$ is the odd number in the sequence.

$264$	$136$	$72$	$40$
$488$	$(a)$	$(b)$	$(c)$

Find out the odd number from the given sequence: $455, 445, 465, 435, 485, 415, 475$.
