In this question you must show all stages of your working. Solutions relying entirely on calculator technology are not acceptable.
In an arithmetic series:
For this series,
find the value of the first term, aaa, and the value of the common difference, ddd.
Hence find the smallest value of nnn for which Sn>5000S_n > 5000Sn>5000.
