Answer:
Step-by-step explanation:
We are to find a formula for the general term of the sequence
We are given that .
- The numerators of these fractions start with 3 and increase by 1. The second term has numerator 4, the third term has numerator 5; in general, the nth term will have numerator 2+n
- The denominators are powers of 5, so
has denominator
- The signs of the terms are alternately positive and negative so we need to multiply by a power of −1. Here we want to start with a positive term and so we use
.
Therefore,
