Let the first even integer be
n.
Then the second even integer be
n+2
The third even integer is x+
4
Given that the sum of the first and the third is 131 less
than 3 times the second.
==> n + (n+4) = 3(n+2) -
131
Now we will combine
terms.
==> 2n + 4 = 3n + 6
-131
==> 4 - 6 + 131 =
n
==> n= 129
==>
n+2 = 131
==> n+4 =
133
Then the integers are 129, 131, and
133
