Answer:
aₙ = -2ⁿ⁻¹
Step-by-step explanation:
Your geometric series is
-1,-2,-4, …
The first term (a₁) is -1, and each successive term is twice the one before it (the common ratio, r)
The formula for the nth term of a geometric series is
aₙ = a₁rⁿ⁻¹
The general formula for your series is then
aₙ = -2ⁿ⁻¹
