from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
