Consider the sequence shown.
Semmy [17]

Given:

The sequence is

436, 218, 109, 54.5, 27.25,...

To find:

The explicit formula for the given sequence.

Solution:

We have,

436, 218, 109, 54.5, 27.25,...

It is a GP because the two consecutive terms have common ratio.

Here,

First term : a=436

Common ratio : d = \dfrac{218}{436}

                             = \dfrac{1}{2}

                             = 0.5

Now, the explicit formula for a GP is

g_n=ar^{(n-1)}

Where, a is the first term and r is the common ratio.

Putting a=436 and r=0.5, we get

g_n=436(0.5)^{(n-1)}

Therefore, the correct option is c.
