Answer:
see explanation
Explanation:
The geometric mean of 2 numbers a and b is
The third term is the geometric mean of the first and fifth terms, that is
a₃ =
= 31.5
The second term is the geometric mean of the first and third terms, that is
a₂ =
= 10.5
The fourth term is the geometric mean of the third and fifth terms, that is
a₄ =
= 94.5
Thus the sequence is
3.5, 10.5, 31.5, 94.5, 283.5
