## Algebra and Trigonometry 10th Edition

$a_n=n(2-\frac{n}{10})$ $a_1=1(2-\frac{1}{10})=2-0.1=1.9$ $a_2=2(2-\frac{2}{10})=2(2-0.2)=2(1.8)=3.6$ $a_3=3(2-\frac{3}{10})=3(2-0.3)=3(1.7)=5.1$ $a_4=4(2-\frac{4}{10})=4(2-0.4)=4(1.6)=6.4$ ... $a_{10}=10(2-\frac{10}{10})=10(2-1)=10(1)=10$ The graph labeled as a matches the sequence.
