it's not the fibonacci sequence (which starts as 1, 1, 2, 3, 5, ..).
in this sequence, the next number is the previous number multiplied by 2. thus you have:
2*2 = 4
4*2 = 8
8*2 = 16

It's called a geometric pregression, or exponential increase. It is where you take anumber and continue doubling it. After several doubling the amoung grows at such a rate that after 3o doublings ti will be over 10,000,000 times larger.
This is different from the fibonocci sequence which runs 1,1,2,3,5,8,13,21,32... where you are adding the munber to the last one in the sezuence then taking that sum and adding it to the next.

the rule is you add the number to itself 2+2=4 then 4+4=8 and so on.

2^x
2006-09-28 12:20:33 · answer #8 · answered by cyrus_xi 5 · 0⤊ 0⤋
2 to the power x - normally written as 2 with the x up above it and to the right (known as superscript)
ie 2 to the power 1 = 2
2 power 2 (or 2 squared) = 4 (2x2)
2 power 3 (or 2 cubed) =8 (2x2x2)
etc
Hope this helps
