I finished halfway but don’t know the test help

a. The terms are;

40, 20 , 10

b. The function will be;

f(x) = f(x-1)/2

Step-by-step explanation:

Here, as we can see, the number of dots in a preceding term is twice the number of dots in the succeeding term

What we mean here is that as we progress, the number of dots in the last term is twice the number of dots in the next term

Firstly, let us fill in the terms written;

That’s ;

40,20,10

The function that determines or describes the pattern is;

Tn =1/2 * Tn-1

or simply put;

f(x) = f(x-1)/2

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

idk
