Vedclass · Answer

(C) The pattern follows an alternating operation of multiplying by $2$ and adding $1$,followed by multiplying by $3$ and adding $1$.$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$ (Instead of $356$)$388 	imes 2 + 1 = 777$Since $356$ does not fit the pattern,it is the odd one out.
