65536...series is 2^1 2^2 2^4 2^9Looking at powers the series is1 2 4 9 i.e. diff of 1 (2-1) 2 (4-2) 5(9-4), so next power term will be 9+7=16..so the next term is 2^16 = 65536

hema, its simple.. this is the logic behind it.. 2 4 16 512
leave 2.... 4 is 2^2, 16 is 2^4, 512 is 2^6, so obviously the next answer should be 2^8 which is 2048.

Ans is 262144 as the next term is square of previous
and no way is 2^6=512, it is 64

1048576 is the answer.
Leaving 2 and 4.
16:-4*4*(2^0)
512:-16*16*(2^1)
So 512*512*(2^2):-1048576

2^1=2
2^2=4
2^4=16
2^6=512
here initially power is odd then even even then odd so cycle is odd even even odd so next vl be even (1+1 = 2) initially now (9+1 = 10) so 2^10= 1024

The given series is 2,4,16,512
which is 2^1,2^2,2^4,2^8.
the powers are multiples of 2. Therefore the next digit is 2^16 65536
