Question

sigma notation help please?

Answer 1

sigma notation in terms of what?

Answer 2

\[\sum_{n=1}^{14}3n+2\]

Answer 3

okay so the sigma in this denotes summation
so for example if you had \[\sum_{x=1}^{4} x ^{2} = 1^{2}+2^{2}+3^{2}+4^{2}\] because you want the SUM of all 'x squared' from x=1 to x=4
so in your question you want the SUM of (3n+2) from n=1 to n=12
so ultimately you want

(3n+2) at n=1 + (3n+2) at n=2 + (3n+2) at n=3 all the way up to n=14

does that make sense?

Answer 4

yes

Answer 5

is there a formula tho?

Answer 6

doesnt look right
