Because they are consecutive, you could say one is "x" and one is "x + 1", then x+(x+1)=179 according to the condition, then x = 89, x+1=90, we found the answer.
X + X+1 = 179 Solve this equation Since consecutive means one after another, x represents the first number, and the consecutive number of X would just be X plus 1 Hope this helps!
