Write an equation to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.
-7, 14/3, -28/9, …
To find the equation that describes the given sequence, we first need to identify the pattern.
We can observe that each term is obtained by multiplying the previous term by -2/3.
So the equation for the given sequence can be written as:
aₙ = (-7) * (-2/3)^(n-1)
Where aₙ represents the nth term in the sequence.
