Answer 1

the series will be
27000, 28100, 29200......
- an increase of 1100 every year
this is an arithmetic series with common diffrence d = 1100

Answer 2

nth term of this series is a + (n-1)d
so 20th term = 27000 + (20-1)*1100

Answer 3

so the answer is 47900? :)

Answer 4

27000 + 19* 1100 = 27000 + 20900

yes

Answer 5

even for 22 years? okay thanks very much! :D

Answer 6

lol - sorry - i used 20 years - my mistake
so add another 2 * 1100

Answer 7

it should be 27000 +(22-1)*1100
= 27000 + 23100 = 50,100 dollars
