Answer:
Step-by-step explanation:
3 yrs ago:
Alice - x
Jane - 3x
Fast forward 2 years... 1 year ago:
Sum of their ages = 62
Equation to solve: x + 3x = 62
4x = 62
----- -----
4 4
x = 15.5
From this, we can deterime that Alice is 15 1/2 years old.
Then, plug in 15.5 for x in 3x to find Jane's age.
15.5 × 3 = 46.5
From this, we can determine that Jane is 46 1/2 years old.
I hope this helps you to understand this problem better.

Answer:
a.Converge
b.Diverge
Step-by-step explanation:
We are given that
Because 
Hence, sequence An converges to 
when n tends to infinity or - infinity.
=diverges
Necessary condition for a series to converge :
when n tends to infinity .
But 
tends to when n tends to infinity.
Therefore, given series is divergent.
