Each of the preceding number is multipied by the previous number

So on multiplying 2*2 = 4
4*2 = 8
8*4 = 32
32*8 = 256
256*32 = 8192
so the answer for this series is 8192

In the series first consider the two terms 2,4
2*4=8 is the third term

Consider 2nd & 3rd terms 4,8
4*8=32 is the fourth term

Similarly 8*32=256 is the fifth term
Hence sixth term is
32*256=8192

Hnce 8192 is the answer

Now the series is in the form of

2,2pw(2),2pw(3),2pw(5), 2pw(7) which is a series of all 2 powers of prime and hence the next no should be 2pw(11) which is 1024*2 = 2048
