What is the nth term in algebra?

The nth term of an arithmetic sequence is given by:—

an = a + (n – 1)d

So, to find the nth term, substitute the given values a = 2 and d = 3 into the formula

it's arithmetic sequence

an = a + (n – 1)d.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
