How do you use the reversal technique to add the first 150 odd integers together?

Why is this in geometry?

What do you mean by the reversal technique? Is this the only method permitted? Do you know how to do a proof by induction?

What does the actual problem say, completely and exactly?

MOST IMPORTANTLY, what have you done already? It is impossible to point out your mistakes or to give a hint for your next step if you do not show us your work.

hhodsonlj, what is shown in this quote box is a set-up for the first 150 integers, so since
you want the sum of the first 150 *odd* integers, you would have to determine what the
151st odd integer is so you can place it correctly in the two places in the diagram.
