Answer:
The series converges to
for
Step-by-step explanation:
Given the series is 
We have to find the values of x for which the series converges.
We know,
converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here,
is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for 
And geometric series converges to 
Here, a = 1 and r = 9x
Therefore, 
Hence, the given series converges to
for 
Answer: ?
Step-by-step explanation:
Answer:
88
Step-by-step explanation:
The original number ⇒ 100
100 is increased by 10%
The result is 20% reduced.
Calculate increase.
100 × (1 + 10%)
100 × (1.1)
= 110
Calculate decrease.
110 × (1 - 20%)
110 × 0.8
= 88
