Find the common ratio and the next term for the sequence shown. Express your answers as fractions or as decimals.
Cerrena [4.2K]
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.
