Forumla for this sequence

[Conrad11]

Hi there,

I am rubbish at maths, does anyone know/can work out the formula for this sequence?

1,2,4,8,16,32,64,128,256.......

i want to be able to get the nth term.

Thanks.

EDIT:

Is there even a formula.

 

[Conrad11]

for (x==1; x<n; x++)
{
x=x*2;
printf(x);
}

Could you please explain what is going on there?

Thanks for all the replies.

This formula worked fine:


2^(n-1)


Thanks again to everyone.
