The value f(5) when f)1) = 3 is f(5) = 43.
How to find the 5th term of the sequence?
The fifth term of the sequence can be found by finding the value of all the terms that precede it.
We can find the value of f(5) as shown below:
The value of f(1) is given as:
f(1) = 3
With this, we can find the value of f(2) and with f(2), we can find the value of f(3), and so on.
f(n) = - 2f(n-1)+1
At n = 2:
f(2) = -2f(2-1)+1
= - 2f(1)+1
= - 2*3 + 1
= - 5
When n = 3:
f(3) = -2*-5 + 1
= 11
When n = 4:
f(4) = -2*11 + 1
= -21
When n = 5:
f(5) = -2*-21 + 1
= 43
Therefore, we have found the value of f(5) to be f(5) = 43.

f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43

The easiest way of solving this is to divide 8% of the number into a % that is divisible by 12.
This is 4%.
So if 8% of the number is 4, then 4 percent is half of 4, that is 2.
Now we convert 4% into 12% thus making it 6
Hope this helps
A more complicated way of doing this, but most reliable is to work out what the number is .
For now let number be y.
8/100 x y = 4
8y/100 = 4
8y= 400
y = 50.
Now calculate 12% of 50.
This is
12/100 x 50 = 6
Hope this helps.

Answer:
Second Option (10° Celsius)
Step-by-step explanation:
There is a formula to convert the temperature which is in degree Celsius into degree Fahrenheit and vice versa. The formula to convert the temperature in degree Fahrenheit into degree Celsius is:
C° = (F° - 32) * 5/9.
It is given that the temperature is 50° Fahrenheit. Therefore, F° = 50°. Substituting F° = 50° in the formula gives:
C° = (50° - 32) * 5/9.
Further simplification results in:
C° = 18 * 5/9. Therefore, C° = 10°.
So the correct answer is 10° Celsius!!!
