3% = 3/100 = 0,03
When it's compount interest it's 1,03 because you gain 3% more from what you already have.
All you need to do
1,03•2000=2060$ for the first year
And then for the second year, you take the actual amount after one year of 3%
1,03•2060=2121,8
After two years, there will be 2121,8$
Each element is 2/3 times the previous one, so that's a geometric sequence.
6×(2/3)=4, 4×(2/3)=8/3, 8/3×(2/3)=16/9, 16/9×(2/3)=32/27
Answer: 6, 4, 8/3, 16/9, 32/27
