The value of (1-d3) / (1-d) is Answers:
A) > 1 if d > -1
B) >3 if d > 1
C) > 2 if 0 < d < 0.5
D) < 2 if d < -2
E) None
Explanation :   Let S = (1 - d3 ) / ( 1 - d ) = ( 1 + d2 + d) .   =&gt; d = 0 then S = 1 .   =&gt; d = 2 then S = 7 .   =&gt; d = 0.1 then S = 1.11 .   =&gt; d = -3 then S = 7 .   Hence, only the option 2 satisfy.   Answer : &gt;3 if d &gt; 1
