The closed formula for <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)

Step-by-step explanation:
It's in the same order, from broker 1 down to broker 5. Straight up
Formula for volume L x W x H
We got them all.
