The exponential function is used. Use x as your variable common ratio.
This is pretty obviously
If it wasn't obvious we can find the common ratio r by dividing successive values:
5/1=5
25/5=5
125/25=5
625/125=5
<h3>What is the common ratio?</h3>
The common ratio is the number you multiply or divide by at each stage of the sequence. You can find it by dividing two consecutive pairs of terms.
That's the common ratio. We multiply by the first term, but the first term is one, so that has no effect.

Answer:
C. 72
Step-by-step explanation:
the answer is C because if you divide 84 by 7 you get 12 so you then multiply 6 by 12 and get 72. the answer could not be negative 72 because that would then make the equation positive.
38 is the correct answer because 80-4=76 then divide that by 76/2 give you 38
