Ms. Stevens gives you an experiment with a plant that starts at 2.5cm tall and asks you to track its growth. After 14 days, your plant measures 23.5cm tall. What is the average rate of change (cm per day) for your plant?

1.5 cm per day

Step-by-step explanation:

23.5-2.5=21

21/14=1.5

(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
