Select the number from among the given options that can replace the question mark (?) in the following series.11, 33, 13, 39, 17, ?

Let's observe the operations performed between consecutive terms in the series:$11\times 3=33$$33-20=13$$13\times 3=39$$39-22=17$ Alternatively, we can see it as pairs where the second term is three times the first term:Pair 1: $(11,11\times 3=33)$ Pair 2: $(13,13\times 3=39)$ Pair 3: $(17,17\times 3=51)$ Therefore, the missing number is $17\times 3=51$.
