Example: Find four consecutive odd integers whose sum is 80.
An odd integer can be written as 2n+1, where n is any integer.
If 2n + 1 is the first odd integer, then add 2 to get the next largest odd integer, and so on.
Now write an equation to solve this problem.
(2n + 1) + (2n + 3) + (2n + 5) + (2n + 7)=-80
Exercises
