I suppose that by sonsecutive you mean consecutive in terms of even nubers.Then we are looking for two numbers 2n and 2n+2 whoose product should be 360. Thus we have 2n*(2n+2) = 360.We could solve for n now, but we are not interested in n we need to know, what 2n equals. So we'll make substitution 2n = x, concluding with x*(x+2)=360. This can be easily solved for x, which yields two solutions 18 and -20. By adding +2 we have second numbers 20 and -18.
That means there are two pairs of numbers possible =>
18 : 20
-18 : -20

The product of two intergers is .
let first one be , and second one be
given:


.....use square root formula








............one slution


..........the other slution

check both solutions:
if , then second integer will be which is
let's check their product:



...........


if , then second integer will be which is
let's check their product:


............in both cases we have correct answer
so, your integers are:
1. and
2. and
