Question 892532: sn problem; above greek symbol is k on the bottom is n=0. Directly next to it is n^2=(k(k+1)(2k+1))/6 check that its correct for k=1,2, and 3.
B.) Use the same formula to compute the value of m=0 top 5 (2m^3+3m-4)
Thank you.

That's the Greek letter sigma, btw. For example:
(2k+1)}{6})
If k = 3, then (7)}{6})
which is a true statement.
Basically, just replace the index (in the above case, n) with its starting value and increment until you get to the top number, and add everything up.
