Question

The product of 2 consecutive #s is 4160 what are the numbers?

Answer 1

64 multiplied by 65 is equal to 4160. You can zero in on the right combination using guess and check.

Answer 2

so the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
