expeople1 [14]

Answer:

a = 256; r = $ \frac{1}{2}  $

Step-by-step explanation:

The general form of the geometric sequence is:

a, ar, ar², ar³, . . .

where 'a' is the first term of the sequence;

'r' is the common difference.

Fourth term of the sequence = ar³ = 32

Sixth term of the sequence   = ar⁵ = 8

Dividing both the equations, we get:

$ \frac{ar^5}{ar^3} = \frac{8}{32} $

⇒ r² = $ \frac{1}{4} $

⇒ r = $ \frac{1}{2} $

Therefore, we get a = 32 X 8

a = 256

The first term of the sequence is 256 and the common difference is $ \frac{1}{2} $.

Hence, the answer.
