Answer:
Divergent
Step-by-step explanation:
Given series has general term as

n+1 th term =
WE have to check whether this series converges or diverges
Let us use ratio test
Ratio of n+1 th term to nth term
=
by dividing numerator and denominator by n square
Take limits as n tends to infinity
The ratio tends to 2
Since ratio >2, the series diverges
Answer:
2
Step by step:
1•2=2
2•2=4
3•3=6
And so on...
Hope this helps!!

Answer:
(c) output increases, then decreases ...
Step-by-step explanation:
The given function is quadratic, so it has a turning point. Neither linear nor exponential functions have a turning point, so are always increasing or decreasing.*
The second attachment shows a plot of the function with input on the x-axis and output (area of the rectangle) on the y-axis.
_____
* A linear function that is a horizontal line will be neither increasing nor decreasing.
Answer:
1. Even - B
2. Even - B
3. Odd - A
Step-by-step explanation:
Example 1: 7+7 = 14
7 is odd, 14 is even.
Example 2: 4 + 4 = 8
4 is even, and 8 is even.
Example 3: 4 + 5 = 9
4 is even, 5 is odd, 9 is odd.
