# Homework Help: Sigma Notation and string of numbers

1. Sep 5, 2006

Trying to help my son & I am in Waaaaay over my head.

He has a string of numbers and needs to come up with the correct Sigma Notation equation.

3, 6, 12, 24, 48, 96

### AKG

$$3\ +\ 6\ +\ 12\ +\ 24\ +\ 48\ +\ 96\ =\ \sum _{k=0}^53\cdot2^k$$

Is that what you wanted? Given a sequence of six numbers, it's not clear what you even mean by "the correct Sigma Notation equation".
