Question

Find the common ratio and the next term for the sequence shown. Express your answers as fractions or as decimals.

333, 250, 187

Answer 1

Answer: The common ratio is 0.750750....

and the next term is 140.390390.....

Explanation:

Since we have given that

333,250,187,....

First we need to find the "Common ratio":

`r=(a_2)/(a_1)=(250)/(333)=0.750`

So, the next term will be

`187* 0.750\\\\=140.390`

Hence, the common ratio is 0.750750....

and the next term is 140.390390.....

Answer 2

The common ratio of the sequence is calculated by dividing the second term by the first term or dividing the third term by the second term. That is,
r = 250 / 333 = 0.75
or r = 187 / 250 = 0.748 = 0.75
To get the next term, we multiply 187 by 0.75 giving us an answer of 140.25 or 141.
