Find the common ratio for the following sequence 20, 10, 5, 2 1/2

0.5

Step-by-step explanation:

We are given the following sequence and we are to determine its common ratio:

20, 10, 5, 2 1/2

In  a sequence, the common ratio is the ratio of a term to its previous term.

So here, we will divide each term by its previous term to find the common ratio.

2 1/2 = 2.5 ---> 2.5/5 = 0.5

5/10 = 0.5

10/20 = 0.5

Therefore, the common ratio of this sequence is 0.5.
