The sun of the first 3 terms of an arithmetic sequence is 21 while their product is 315 determine these three terms?

The terms of the sequence are x=5 and a=2:

 →  

 →  

Step-by-step explanation:

We can find the terms of the following sequence:

     (1)

The product of that sequence is:

   (2)

Solving equation (1) for x:

 (3)

And by entering (3) into (2):

Now, by entering "a" into equation (3):

Therefore, the terms of the sequence are x=5 and a=2.

I hope it helps you!

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
