Answer:
aₙ = 40*(1/2)ⁿ⁻¹
Step-by-step explanation:
<u>As per graph we have:</u>
<u>So the first term is </u><u>40</u><u> and common ratio is </u>
<u>Formula for nth term is:</u>
6
7.5*5=37.5
200/37.5=6
- 5
Substitute the given values into the expression
ax + by
= (- 2 × 1) + (3 × - 1)
= - 2 + (- 3)
= - 2 - 3
= - 5
