Answer: 3
The answer is three, do you need me to show you how I solved it?
The three even integers are 80, 82, and 84.
The sum of the first (80) and the third (84) integers = 80 + 84 = 164, verifying our answer.
A simple way to figure this out is to divide 164 by 2, which gives you 82. From this answer, if we subtract 2 to get the first integer and add 2 to get the third integer while keeping 82 as the second integer, we end up with the correct sum of 164.
Hope this helps!
