The given sequence is a geometric sequence, where each term is obtained by multiplying the previous term by a fixed ratio. In this case, the ratio is 3/4.
Therefore, the equation to describe the sequence is:
an = (5/2) * (3/4)^(n-1)
Therefore, the equation to describe the sequence is:
an = (5/2) * (3/4)^(n-1)
