Hi,
Susan started a job that paid $30,000 a year
Each year after the first, her salary increased by 4%.
what is Susan's salary in his sixth year of employment...?
a%5Bn%5D+=+a%5B1%5D%2Ar%5E%28n-1%29
a%5B6%5D+=+30000%281.04%29%5E%285%29 = $36,499.59
sum%28+a%5Bn%5D%2C+i=1%2C+6+%29+=+a%5B1%5D%28%281-r%5En%29%2F%281-r%29%29
30000%28%281-%281.04%29%5E6%29%2F%28-.04%29%29 = $198,989.26
