Answer 2

Step-by-step explanation:

Let the second term be x

We are given that the first term is half of second term

So, First term = x/2

We are given that The third term is twice the second term

So, Third term = 2x

Now we are given that the average of 3 terms is 28

So,

Third term = 2x=2(24)=48

Hence the third term is 48
