If 
= b, then
A
= e –2
B
C
{(– a) n + b n )} 1/n = 2
D
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c, d)
= b
⇒ 
= b
as the given limit is a finite number so a + 1 = 0
∴ a = – 1
Now 
= b ⇒ b = 2
= 
= 
= e –2
= 
= 
{(– a) n + b n } 1/n = 
{1 + 2 n } 1/n
= 
= 
= 
= 
= 
= 2 ×
