Question 1090992: The expression 2n+1 represents an odd integer. Write an expression to find three consecutive odd integers whose sum is 63.
I know the answer to be 19, 21, and 23. If I use n+n+2+n+4=63. I can't make the 2n+1 work.

The expression 2n+1 represents an odd integer. Write an expression to find three consecutive odd integers whose sum is 63.
I know the answer to be 19, 21, and 23. If I use n+n+2+n+4=63. I can't make the 2n+1 work.
----------
2n+1 is an odd number for all integers n.
You don't have to make it work.
========================
Write an expression to find three consecutive odd integers whose sum is 63.
---
n + n+2 + n+4 = 63 The hard way
-----
n-2 + n + n+2 = 63 Better
----
63/3 = 21, the middle integer, the Best way.

n represents any integer as far as i know.
the odd number is represented by 2n + 1
that would be the first number.
the second odd number would be 2n + 3
the third odd number would be 2n + 5
you get 2n + 1 + 2n + 3 + 2n + 5 = 63
combine like terms to get 6n + 9 = 63
subtract 9 from both sides to get 6n = 54
divide both sides by 6 to get n = 9
when n = 9:
2n + 1 = 19
2n + 3 = 21
2n + 5 = 23
