Question

5
∑ 2n+1 =
n=1
What is the answer to this equation and how do you solve it?

Answer 1

The given equation is a summation notation that represents the sum of the expression 2n+1 for n=1 to n=5.

Substituting the values of n into the expression and adding them up, we get:

2(1) + 1 + 2(2) + 1 + 2(3) + 1 + 2(4) + 1 + 2(5) + 1 = 5 + 9 + 13 + 17 + 21 = 65

Therefore, the answer to the given equation is 65.
