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)
</span>
If you mean as a decimal, it's 30.125.
Answer:
n/2 - 6 + 10
8/2 - 6 + 10
4 - 6 + 10
= 8
