Answer:

5050

Explanation:

To solve via calculator, go to the MATH menu, then the 0th option should say "summation" and insert it from there.

To solve algebraically, break the summation into 2 parts. Excuse the strange formatting, I can't find a way to do it normally.

4(
(50)/(1)∑n) -

= 4(
(50(50+1))/(2)) - 50(1)

= 5100 - 50

= 5050
