Summing four consecutive numbers and getting 80 is simply impossible. If you sum 1+2+3+4, then you get 10, and when you add 1 to each number to get new consecutive numbers, the answer gets higher by 4, so the answers are:
10, 14, 18, 22, 26, 30 and so on, so the numbers don’t reach a multiple of 4, because the first number (10) is not a multiple of 4, and since they keep adding by 4, you can never sum 4 consecutive numbers and get a multiple of 4.

To conclude, not only summing 4 consecutive numbers is impossible, but summing 4 consecutive numbers and getting any multiple of 4 is impossible.
