find an expression for the area under the graph of f(x)= (x^2)+x from x=2 to x=5 as a limit of a riemann sum (do not need to evaluate).

Question

the answer i got was:
lim as x-> infinity of sigma from i=2 to n of (2+3i/n)^2+(3i/n)(3/n)

is this correct?

Answer 1

sorry, I typed the answer wrong. Can you please check this answer?

lim as x-> infinity of sigma from i=2 to n of ((2+3i/n^2+(2+3i/n))(3/n)
