So I have a formula,
100n(50×(1+100(n−1)))=a(n)
for finding the nth term of the sequence, but since It's neither arithmatic nor geometric, I don't know how to find a formula for the sum of the nth terms. Is there even a way to?
I can't find an exact formula for the sum of N terms, but there is an approximate expression:
sum ≈ 2*N - 1.02 which gives it to two decimal places.
or sum ≈ 2*N - 1.020004 which gives it to 6 decimal places for N>3
.
