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

ANSWER: The cost of the wings in dollars per wing would be $1.25.
