Respuesta :
For the sum of the given geometric series a₁ = -4 and r = -2.
What is Geometric Series?
- It is the sum of geometric sequence of finite or infinite sequence.
- The ratio between two adjacent number for any sequence is constant.
Given: Geometric Series
−4, 8, −16, 32,…
First term is:
⇒ a₁ = -4
For the geometric series, the ratio is constant.
Ratio is given by:
⇒ r = 8/-4 = -16/8 = 32/-16
⇒ r = -2
Therefore, for the given geometric series a₁ = -4 and r = -2.
