Jon's office had already recycled 29 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 3 kilograms of paper each week. How many weeks will it take Jon's office to recycle a total of 44 kilograms of paper?

5

Step-by-step explanation:

44 - 29 = 15

15 \ 3 = 5

(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
