rewrite in expanded form please
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
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?
I'm just going to write it out to make sure this is clear. You're looking for:\[ (2\cdot1^2+1)+(2\cdot2^2+1)+(2\cdot3^2+1)+(2\cdot4^2+1)+(2\cdot5^2+1) \]
Do you understand how I got that?
nbouscal is this he answer 3,9,19,33,51 or do i add them equalling 115
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.
Samm, are you looking for 1 number or 5?
road: Neither, the question says to write it in expanded form.
Ok, my brain is pooped.
