Question 143389
First integer: x
Second integer: x + 1
Third integer: x + 2


Twice the second: 2(x + 1)
...and increased by the first: 2(x + 1) + x


is (meaning equals) 35, so:


{{{2(x + 1)+x=35}}}.  Just solve for x to get the first integer and the other two follow.


3 consecutive odd integers whose sum is 171.


First odd integer: x
Second odd integer: x + 2
Third odd integer: x + 4, so


{{{x + x + 2 + x + 4 = 171}}}, solve for x to get the first integer.
