- summation - The idea behind the sum of powers of 2 - Mathematics Stack . . .
I know that the sum of powers of $2$ is $2^{n+1}-1$, and I know the mathematical induction proof But does anyone know how $2^{n+1}-1$ comes up in the first place For example, sum of n numbers is
- summation - Intuition behind the formula for $\sum_{i=1}^n i^{2 . . .
Since you asked for an intuitive explanation consider a simple case of $1^2+2^2+3^2+4^2$ using a set of children's blocks to build a pyramid-like structure

- Sum of a series of a number raised to incrementing powers
late to the party but i think it's useful to have a way of getting to the general formula this is a geometric serie which means it's the sum of a geometric sequence (a fancy word for a sequence where each successive term is the previous term times a fixed number) we can find a general formula for geometric series following the logic below

$\displaystyle\sum_{i,t}$ means the same as $\displaystyle\sum_i \sum_t$ In the second notation, a specific summation order is given, whereas in the first one there isn't So the first notation is only appropriate if the order of summation doesn't matter For example in the finite case

When we deal with summation notation, there are some useful computational shortcuts, e g : $$\\sum\\limits_{i=1}^{n} (2 + 3i) = \\sum\\limits_{i=1}^{n} 2 + \\sum
