Question

Expanding and simplifying sequences

Answer 1

\[\sum_{k=0}^{5}2k \]

Answer 2

what you do is plug in k = 0, k = 1, k = 2... all the way up to k = 5

so...

k = 0 ---> 2k = 2*0 = 0
k = 1 ---> 2k = 2*1 = 2
...
...
k = 5 ---> 2k = 2*5 = 10


then you add up all those results

Okay. Thank you!
