Take it from there.

Answer 2

please give better explanation, if possible.

Answer 3

Did you find the cube root of 4080?

What is it?

Answer 4

If we say that the middle value is n

then
(n-1)n(n+1)=4080

so

n^3-n-4080=0

there are the several approaches to use.

Using Ms Sue's approach is to say that

n is approximately cuberoot(4080)=15.98

we can then use 16 and adjust from there. Luckily (?) we then find the three numbers are 15, 16, 17.

Does this help?
