Question

rewrite in expanded form please

Answer 1

\[\sum_{m=1}^{5}(2m ^{2}+1)\]

Answer 2

Uh, expanded form? As in the sequence? You only have 5 terms so it's a sequence but you have sigma which leads me to believe that it's a sum

Answer 3

You're looking for the sum of (2m^2+1) for each of m=1 through m=5. So it will start with \((2\cdot1^2+1)\), can you take it from there?

Answer 4

3,3+9,12+19,etc

Answer 5

I'm just going to write it out to make sure this is clear. You're looking for:\[
(2\cdot1^2+1)+(2\cdot2^2+1)+(2\cdot3^2+1)+(2\cdot4^2+1)+(2\cdot5^2+1)
\]

Answer 6

Do you understand how I got that?

Answer 7

nbouscal is this he answer 3,9,19,33,51 or do i add them equalling 115

Answer 8

They are summed, but the question is not asking for the solution, it is asking for the expanded form of it, which is what I wrote in my previous reply.

Answer 9

Samm, are you looking for 1 number or 5?

Answer 10
