Read Solution (Total 11)
-
- consider 2 as 2 power 0
then 4 as 2power 2
then 8 as 2 power 3
then 32 as 2 power 5
then 256 as 2 power 8
So if we consider the power values they are like Fibonacci series(1,2,3,5,8,?)
if we add the first 2 values we get the next one as follows
1
2
1+2=3
2+3=5
3+5=8
5+8=13
=>2 power 13 =8192(answer). - 10 years agoHelpfull: Yes(2) No(0)
- 2*2=4
4*2=8
8*4=32
32*8=256
256*32=8196

- 2^1=2
2^2=4
2^(1+2)=2^3=8
2^(2+3)=2^5=32
2^(3+5)=2^8=256
2^(5+3)=2^13=8192 - 9 years agoHelpfull: Yes(0) No(0)
- Multiply 1*2,2*3,3*4,4*5,5*6=8192
