You need to use the addition formula when the last term is not given. Mind you, you could find it, but it is just as easy to get the answer without it.
Givens
a1 = 2
d = 3
n = 36
Formula
Sum = n(a1 + (n - 1)* d)/2
Solution
Sum = 36(2 + (36 - 1)*3 )/2 Combine the brackets
Sum = 36 (2 + 35*3 )/2
Sum = 36(2 + 105) /2 Combine the brackets
Sum = 36 * 107/2
Sum = 3852 /2
Sum = 1926
Answer
1926
So we know that 2+2=4 and then we multiply that by 2 and then by X3, where we get 24X. Then we must subtract 16 from 1234322, which is 1234306. So we add 1234306 to 24X and get 24X+1234306 as our answer.

Answer:
f(-3) =17
Step-by-step explanation:
f(x)=2x^2-1
Let x = -3
f(-3)=2(-3)^2-1
= 2(9) -1
= 18-1
17
1. a(x+b)
2. ax+ab
example:
2(x+3)
=2.x + 2.3
=2x + 6
