If two consecutive numbers add up to 86 then we can set up an equation like this:
x=the first number
So it makes sense that
x+2=the second number (since the numbers are consecutive)
And you know the sum of the two is 86. So the resulting equation is
(x) + (x+2) = 86
=>
2x + 2 = 86
2x = 84
x = 42
So the two numbers are 42 and 44.

There are no two consecutive even integers, consecutive odd integers, or consecutive integers that satisfy that relationship.
44 & 45
27, 29
Divide the sum of the two consecutive even integers by 2: 90/2 = 45. The smaller of these integers will be one less than 45 and the larger will be one more than 45, so the two consecutive even integers will be 44 and 46.
x + 3(x +1) = 330 4x = 327 which doesn't give an answer in integers. If question should read "consecutive ODD integers" the answer would be 81 and 83.
