Hi,
Jhon started a job that paid $20,000 a year. Each year after the first, he received a raise of $600.
What is jhon's salary in his tenth year of employment...!?
a%5Bn%5D=a%5B1%5D%2B%28n-1%29%2Ad
a%5B10%5D=20000+%2B%289%29%2A600= $25,400
What was the total amount jhon earned in ten years...!?
S%5Bn%5D=%28n%28a%5B1%5D%2Ba%5Bn%5D%29%29%2F2
S%5B10%5D=+5%2820000%2B25400%29 = $227,000
