Answer:
1
Step-by-step explanation:
Since all 5 terms are like terms they can all be combined into 1 term. For example, 3x + 8x + 5x + 4x + 19x = ?. Since they all have the term x they can be combined into 39x. That leaves 1 term.
It is 33% because the probability is 1/3.
The explicit formula for this geometric sequence is 27.3(n-1)
