Answer:
n(n+1)
Step-by-step explanation:
Only the last two formulas work for n=1; only the last formula works for n=2.
<u>For n=1</u>
3n = 3 ≠ 2
n² -1 = 0 ≠ 2
n² +1 = 2
n(n+1) = 2
<u>For n=2</u>
n²+1 = 5 ≠ 6
n(n+1) = 6 . . . . . this last formula works for the given sequence

Answer:
Step-by-step explanation:
The formula of a slope:
If
m > 0, then a line is rising

m = 0, then a line is horizontal
m is undefined, then a line is vertical
<h2>a.</h2>

<h2>c.</h2>
(2, 1) and (-3, 1)

<h3>Answer:</h3>
It depends:
- 4 if she starts at 4
- 5 if she starts at 0
<h3>Explanation:</h3>
Louise needs to end up a total of 5 times 4 away from zero.
If she starts at 4, which is 1 times 4, then she needs to jump 4 more times, to 2, 3, 4, 5 times 4.
If she starts at 0, then she needs to jump 5 times to 1, 2, 3, 4, 5 times 4. (The values at the end of each jump will be {4, 8, 12, 16, 20}.)
