The sum of the second and fifth terms of a geometric sequence is 3.2. The sum of the third and the sixth is -7. Determine the ratio (r) of the sequence and the first term (a)?

If a geometric sequence starts with 'a' and the ratio is 'r' (a, ar, ar[sup:sy0roqpj]2[/sup:sy0roqpj], ar[sup:sy0roqpj]3[/sup:sy0roqpj].....) then

what is the second term?

What is the third term?

What is the fifth term?

What is the sixth term?

what is the sum of the second and fifth terms (expressed as functions of 'a' and 'r')?

what is the sum of the third and sixth terms (expressed as functions of 'a' and 'r')?

Please show us your aork, indicating exactly where you are stuck, so that we know where to begin to help you.
