twice a number y is more than 5/2

an inequality is

Step-by-step explanation:

2y >= 5/2

Step-by-step explanation:

twice a number y, is more then 5/2...

2y > 5/2y > (5/2)/2...y > 5/2 * 1/2y > 5/4 <==

(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
