Step-by-step explanation:

If there is a common ratio between consecutive terms in the sequence then it is geometric, that is

$\frac{28}{196}$ = $\frac{1}{7}$

$\frac{4}{28}$ = $\frac{1}{7}$

$\frac{4}{\frac{4}{7} }$ = 4 × $\frac{7}{4}$ = 7

There is not a common ratio between consecutive terms, thus

The sequence is not geometric
