The question is not correctly written
Correct Question
The equation aₙ= r ∙ aⁿ⁻¹ is the _______________ formula for a geometric sequence.
Answer:
nth formula of a geometric sequence.
Step-by-step explanation:
A geometric sequence is a sequence of given numbers that has consistent or the same common ratio between the numbers.
A geometric sequence can also be referred to or called a geometric progression.
In other to be able to correctly to solve a question on geometric sequence, we need to use the formula called "nth term of a geometric sequence".
The formula is given as: aₙ= r ∙ aⁿ⁻¹
where
aₙ= nth term
r = Common ratio between the given numbers in the geometric sequence which is calculated as a₂/a₁ = a₃ /a₂
a₁ = first term
n = number of terms
