A. The value of a book is $340 and
decreases at a rate of 7% each year. Find
the value of the book after 9 years?
b. The average price of a gallon of milk is
$3.31. If the price of milk increases .88%
each year, how much will a gallon of milk
cost in 20 years?

a. $190.3

b.  $3.94

(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
