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 sequence can be represented as follows:
a) For even values of n: (-1)^n * 3^(n-1)
b) For odd values of n: (-1)^(n+1) * 3^(n-1)
Using the above equations, we can find the value for any position n in the sequence.
