The sequence 5, 10, 20, 40 … shows the number of “likes” on a viral video each day starting with the day it was published. a) what is the recursive rule for the sequence? b) what is the explicit rule for the sequence?

a) , where .

b)  

Step-by-step explanation:

The given sequence is

.

The first term of the sequence is

The second term is

The common ratio for this sequence can be determined using any two consecutive terms in the sequence.

Using the first two terms, the common ratio is

a) The recursive rule is given by,

, where .

b) The explicit rule is given by

a 10 percent increase

ab will be equal to
