Let the first odd integer be x.
Then, "consecutive odd integers" are x, (x+2), (x+4), (x+6), (x+8), etc. [add 2 because they are odd]
"sum of the first, second, and fourth is 47" means
x + (x+2) + (x+6) = 47
3x + 8 = 47 [collect terms]
3x = 39 [subtract 8 from both sides]
x = 13 [divide both sides by 3]
Now, find the other two numbers.
The three odd integers are: 13, 15, 19
Check:
Is 13 + 15 + 19 = 47 ?
47 = 47 ?yes
