(D) Let us analyze the pattern of the series:$1 	imes 2 + 1 = 3$$3 	imes 3 + 1 = 10$$10 	imes 2 + 1 = 21$$21 	imes 3 + 1 = 64$$64 	imes 2 + 1 = 129$$129 	imes 3 + 1 = 388$$388 	imes 2 + 1 = 777$ (Note: The series logic follows $	imes 2+1, 	imes 3+1$ alternately).Comparing this with the given series $1, 3, 10, 21, 64, 129, 256, 778$,we see that $256$ is the incorrect term as the expected term after $129$ is $388$.

Find out the wrong term from the given series.
$1, 3, 10, 21, 64, 129, 256, 778$
