Question

Please help me with this

Answer 1

see explanation

Explanation:

The geometric mean of 2 numbers a and b is
`√(ab)`

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

a₃ =
`√(3.5(283.5))` = 31.5

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

a₂ =
`√(3.5(31.5))` = 10.5

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

a₄ =
`√(31.5(283.5))` = 94.5

Thus the sequence is

3.5, 10.5, 31.5, 94.5, 283.5
