A diver is 4 meters below sea level. What integer represents the location of the diver?

-4

Step-by-step explanation:

When talking about integers key words like below or anything being  Loss means Negative.And anything relating to an positive like   above or receive means positive which means anything  that your gaining or getting.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
