4) A sequence is defined recursively by f(1) = 2and f(n) = 3f(n-1) + 1. Find the first three
terms of the sequence.
- How do I do this question and just Recursive Sequences in general?

Let me explain why.
this is our first term.
second term.
third term.
...
Pretty simple huh?
Hope this helps.
Answer:
The first 3 terms are 2, 7, 22.
Step-by-step explanation:
The n is the sequence number of the term: f(1) means the first term.
The second term
f(2) = 3f(n - 1) + 1 We make n = 2:
= 3f(2-1) + 1
= 3f(1) + 1 f(1) = 2 so:
= 3*2 + 1
= 7.
3rd term f(3)
= 3f(3 - 1) + 1
= 3f(2) + 1
= 3(7) + 1
= 22.

Answer:
if red = 1 white = 4/3 or 1 1/3
if white = 1 red = 3/4
if red = 4 white = = 16/3 = 5 1/3
if white = 5 red = 15/4 = 3 3/4
Step-by-step explanation:
white 4
--------= ---------
red 3
if red = 1
white 4
--------= ---------
1 3
using cross products
white *3 = 4*1
divide by 3
white = 4/3
if white = 1
1 4
--------= ---------
red 3
using cross products
3*1 = 4* red
divide by 4
3/4 = red
if red = 4
white 4
--------= ---------
4 3
using cross products
white *3 = 4*4
white *3 = 16
divide by 3
white = 16/3 = 5 1/3
if white = 5
5 4
--------= ---------
red 3
using cross products
3*5 = 4* red
15 = 4 * red
divide by 4
15/4 = red
3 3/4 = red

7(4x) - 9 = -6
28x -9 = -6
28x = 3
x = 3/28
OR
7 + 4x - 9 = -6
4x - 2 = -6
4x = -4
x = -1
Hope that helps :)
7 + 4x - 9 = -6
Subtract 7 on both sides.
4x - 9 = -13
Add 9 on both sides.
4x = -4
Divide by 4 on both sides.
x = -1
or
7 - 4x - 9 = -6
Add 9 on both sides.
7 - 4x = 3
Add 4x on both sides.
7 = 4x +3
Subtract 3 on both sides.
4 = 4x
Divide by 4 on both sides.
x = 4

Final answer:
In the scenario, a right triangle is formed with the board, the ground, and the wall. We use the Pythagorean theorem to find the height the board will reach up the wall and get the result as 8 feet.
Explanation:
This is a geometry problem where we need to determine the height the board will reach up the wall. This appears to be a right triangle since the board is leaning against the wall. The length of the board is the hypotenuse (10 feet), and the distance from the wall is one of the legs of the triangle (6 feet).
To find the height the board will reach up the wall, which is the other leg of the triangle, we can use the Pythagorean theorem: a² + b² = c² where a and b are the legs and c is the hypotenuse.
Substitute the given values to the formula: a² + 6² = 10²
Solving this equation gives: a² = 10² - 6²
Then, a² = 64
So, a = √64 = 8
Thus, the height the board will reach up the wall is 8 feet.
