2. Use the ideas in drawings (a) and (b) to find the solution to Gauss's Problem for the sum 1 + 2 + 3 + ... + n. Explain
your reasoning.

Step-by-step explanation:

Hello, I will compute twice the sum so I need to compute,

1+n = n+1

2 + n-1=n+1

...

n-1+2=n+1

n+1=n+1

So, this is n times n+1 so it is n*(n+1)

one set of data has more variation than the other. hope this !
