Beginning with Rodney's first month of high school, his father deposits $5 into Rodney's savings account. Each month after the first month, his father deposits $2 more than the previous month. The total amount deposited in Rodney's
account after four years can be represented using the expression 2 [5+2(n-1)]. How much total money has been
48
n=1
deposited?
$2,496
O $2,544
O $2,640
O $2,688
Yes

(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
