Meg found another treasure between −13 4
feet and
-21
2
feet. Where was that treasure?

Negative 1 and one-half
Negative 2 and three-fourths
Negative 1 and one-fourth
Negative 2 and one-fourth

Step-by-step explanation:

if it's -1 and 3/4 and -2 1/2 then it would be D, it's the only number to fit in that range

(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
