Answer: GP = ar^n-1
To find r , divide the 2nd term by the 1st term or the 3rd term by the 2nd term.
Now r = 3/4 or g/3. To find g now, the two can be equated together and solve for g or by multiplying the 2nd term by the common ratio.
(1) r = 3/4 ……………………,(1)
r =. g/3……………………..(2)
g = 3/4 x 3
= 9/4. or
3/4 = g/4, by cross multiplying the equation, it now becomes
4g = 3 x3
4g = 9
Now divide both dude by the coefficient of g which is 4
g = 9/4
Now, r = 3/4 or g/3 and g = 9/4
