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)

Answer:
242
First is 9 times 10 which is 90, then 4 times 8 is 32 divided by 2 which is 16 times 2 since there are two, 32 again. 8 times 10 is 80. 4 times 10 is 40.
90 + 32 + 80 + 40 = 242
