Step-by-step explanation:

The geometric mean of 2 numbers a and b is $\sqrt{ab}$

The third term is the geometric mean of the first and fifth terms, that is

a₃ = $\sqrt{3.5(283.5)}$ = 31.5

The second term is the geometric mean of the first and third terms, that is

a₂ = $\sqrt{3.5(31.5)}$ = 10.5

The fourth term is the geometric mean of the third and fifth terms, that is

a₄ = $\sqrt{31.5(283.5)}$ = 94.5

Thus the sequence is

3.5, 10.5, 31.5, 94.5, 283.5
