The second and fifth term of a geometric progression are 3/2 and 1/12 respectively. What is the first term?

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
