what do you know about even numbers? They differ by 2, right?
So, if the smaller number is x, then the larger one is x+2
x(x+2) = 288
now solve that.
Or, if you consider u as the number between the two even ones, then
(u-1)(u+1) = u^2-1 = 288
u^2 = 289
u=17
so the numbers are 16 and 18.
Two consecutive even numbers have a product of 288. What are the numbers?
The answer I got through trial and error was 18 and 16. Is there a way for me to form the question into an equation and work that out to find the answer, instead of just guessing numbers? Thanks.
