Question

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

Answer 1

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. 

Answer 2

Answer: The common ratio is 0.750750....

and the next term is 140.390390.....

Step-by-step explanation:

Since we have given that

333,250,187,....

First we need to find the "Common ratio":

$r=\frac{a_2}{a_1}=\frac{250}{333}=0.750$

So, the next term will be

$187\times 0.750\\\\=140.390$

Hence, the common ratio is 0.750750....

and the next term is 140.390390.....
