The next number of the sequence 3, 5, 9, 17, 33 …. is :

The next number of the sequence 3, 5, 9, 17, 33 …. is :
[A]49
[B]60
[C]65
[D]50

65
3\xrightarrow{+2}5\xrightarrow{+4=2^{2}}9\xrightarrow{+8 = 2^{3}}17\xrightarrow{+16= 2^{4}}33\xrightarrow{+32 = 2^{5}}\underline{65}
∴ The next term in the sequence will be 65.
Hence option [C] is the right answer.
