Answer:

5050

Step-by-step 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([tex]\frac{50}{1}[/tex]∑n) -

= 4( [tex]\frac{50(50+1)}{2}[/tex]) - 50(1)

= 5100 - 50

= 5050
