Single Variable Calculus

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).
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?

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)
