Question:
Use theorem 4.1.6 to show that {sn} converges.
a)  (β0) =
CASE 1
α>β

THEN SERIES IS NON INCREASING.HENCE AS PER
Theorem 4.1.6
(a) if {sn} is nondecreasing, then ==S(1)=(1+α)/(1+β)...=FINITE VALUE
HENCE CONVERGENT
CASE 2
α<β
THEN SERIES IS NON DECREASING.HENCE AS PER
Theorem 4.1.6

(b) if {sn} is nonincreasing, then ==S(1)=(1+α)/(1+β)...=FINITE VALUE
HENCE CONVERGENT
