(C) The given series is $39, 52, 78, 117, 169, ?$. We can observe the pattern by dividing each term by $13$: $39 = 13 	imes 3$ $52 = 13 	imes 4$ $78 = 13 	imes 6$ $117 = 13 	imes 9$ $169 = 13 	imes 13$ The multipliers are $3, 4, 6, 9, 13$. The differences between these multipliers are: $4 - 3 = 1$ $6 - 4 = 2$ $9 - 6 = 3$ $13 - 9 = 4$ The next difference should be $5$. So,the next multiplier is $13 + 5 = 18$. Therefore,the missing term is $13 	imes 18 = 234$.
