Calculate number sequence

mr_malee · 2014-08-14T01:16:57

Hi, was wondering if there's a more mathematical approach to calculating a sequence of numbers where each number multiplies itself by 2. so starting with the number 5, and running 6 levels you would end up with 5, 10, 20, 40, 80, 160 I've got this and it works, but wondering if there's a more efficient way of doing it? int n = 5; int level = 6; for (int i = 1; i < level; i++) { n *= 2; } return n; thanks

ah Thanks. Here's what I ended up with


if (index == 0) {
			
	return 1;
}

int v = (index - 1) / 4;
int n = (index - 1) % 4;
int m = (int)Mathf.Pow(60, v);

if (n == 0) {

	return 5 * m;
}
else if (n == 1) {

	return 10 * m;
}
else if (n == 2) {

	return 30 * m;
}
else if (n == 3) {

	return 60 * m;
}
