What is the value of the fourth term in a geometric sequence for which a1= 30 and are= 1/2?

15/4.

Step-by-step explanation:

4th term = a1 r^3

= 30(1/2)^3

= 30/8

= 15/4.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
