Minus 5 from both sides so we have 3a=-19 now divide both sides by 3 so we have a=-6 1/3
I think 63, but I'm not sure, how do I delete an answer-
Answer:
This is an geometric sequence with a common ratio <em>r</em> of 1/2
Step-by-step explanation:
When you find out <em>r</em>, you realize the ratio between the numbers to be dividing by 2, or 1/2. Since it is <em>r</em> and not common difference <em>d</em>, it is an geometric sequence.
A. the outlier is 37
