n is an integer.
First, 2n+1
Second, 2n+3
Third, 2n+5

5%282n%2B1%2B2n%2B3%2B2n%2B5%29=66%2B%282n%2B1%29%282n%2B3%29
That is the description transcribed into an equation.

Simplify and solve for n, and then evaluate the three positive integers.

Find three consecutive odd positive integers such that 5 times the sum of all three is 66 more than the product of the first and second integers.
Let the smallest integer be S
Then other 2 are: S + 2, and S + 4
We then get: 5(S + S + 2 + S + 4) = S(S + 2) + 66
5%283S+%2B+6%29+=+S%5E2+%2B+2S+%2B+66
15S+%2B+30+=+S%5E2+%2B+2S+%2B+66
S%5E2+%2B+2S+-+15S+%2B+66+-+30+=+0
S%5E2+-+13S+%2B+36+=+0
(S - 9)(S - 4) = 0
S, or smallest integer = highlight_green%289%29 OR S = 4 (ignore)
Middle integer: 9 + 2, or highlight_green%2811%29
Largest integer: 9 + 4, or highlight_green%2813%29
