The sum of the series a)49/25b)49/24c)47/24d)49/29Correct answer is op...
(1 + 1/52) + (1/2 + 1/52) + (1/22 + 1/54)+......
= (1 + 1/2 + 1/22 +....) + (1/52 + 1/54 + 1/56 +......)
= r = (1/4)/(1/2) , r = (1/54)/(1/52)
⇒ r = 1/2 + 1/25
⇒ S = 1 + [(1/2)/(1-1/2)], S = [(1/25)/(1-1/25)]
⇒ S = 1 + 1, S = 1/24
Total sum = 2 + 1/24
⇒ 49/24
= (1 + 1/2 + 1/22 +....) + (1/52 + 1/54 + 1/56 +......)
= r = (1/4)/(1/2) , r = (1/54)/(1/52)
⇒ r = 1/2 + 1/25
⇒ S = 1 + [(1/2)/(1-1/2)], S = [(1/25)/(1-1/25)]
⇒ S = 1 + 1, S = 1/24
Total sum = 2 + 1/24
⇒ 49/24
