Question

write the terms of the series and find they sum (pic)

Answer 1

so you want to plug in 1 for k....and find out what it =...then plug in 2...then 3....then 4 because that 4 on top of "sigma" means the last number in the sequence

so when you sub in 1 for k you get?
what about 2?
3?
4?

Answer 2

plug in 1 to the equation then 2 then 3 then 4 \[\sum_{k=1}^{4} (1+9)^2,+ \sum_{k=2}^{4}(2+9)^2, +\sum_{k=3}^{4}(3+9)^2, +\sum_{k=4}^{4}(4+9)^2\]

Answer 3
