write an equation to decribe the sequence below. use n to represent the position of a term in the sequence, where n=1 for the first term
1, -3,9,
write your answer using decimals and integers
The given sequence is 1, -3, 9.
If we observe carefully, we can see that each term in the sequence is obtained by multiplying the previous term by -3.
Using this pattern, we can write the equation to describe the sequence as:
aₙ = (-3)^(n-1)
Where aₙ represents the nth term in the sequence.
Therefore, the equation for the given sequence is aₙ = (-3)^(n-1).
