------
1st:: 2x-3
2nd:: 2x-1
3rd:: 2x+1
4th:: 2x+3
-------------------
Equation:
(2x-3)+(2x-1) = 4(2x+3)
4x-4 = 8x+12
4x = -16
x = -4
-----
3rd = 2x+1 = -7

Find the third of four consecutive odd integers given that the sum of the first two integers if four times the larger
Let smallest integer be S
Then others are:
S + 2
S + 4
S + 6
From the description. S + S + 2 = 4(S + 6)
2S + 2 = 4S + 24
2S - 4S = 24 - 2
- 2S = 22
S, or smallest integer = , or - 11
Third integer: - 11 + 4, or
