Verified Answer
Consider an infinite geometric series with first term a and common rat...
Sum = 4 and second term = 3/4, it is given that first term is a and common ratio r
 = 4 and ar = 3 /4 ⇒ 
Therefore, 
or a2 – 4a + 3 = 0 ⇒ (a – 1)  (a – 3) = 0
⇒ a = 1  or  3
When a = 1, r = 3/4 and when a = 3, r = 1/4
