Given
Every other minute
Required
Determine the recursive function
Let the number of minutes be represented with n.
The initial condition can be represented as:
--- i.e. 3 friends initially at the first minute
At every other minutes:
i.e 2 minutes upwards
This means that n follows the following sequence
Note that the difference between each term is 1.
This means that recursive function has to be defined backwards i.e.
Where k = 2
i.e. The number of friends that received the video from each friend
So, we have:
Hence, the recursive function is:

Answer:
x = 7.5 Hope This Helps :)
Step-by-step explanation:
3(x + 4.5) = 36
3x + 13.5 = 36
3x + 13.5 = 36
- 13.5 - 13.5
3x = 22.5
3x/3 = 22.5/3
x = 7.5
Answer:
The value of A5 is 25
Step-by-step explanation:
L = a1 + (n - 1) x d
a1 = 9 n = 5 d = 4
L = 9 + (5 -1)x4
L = 9 + 4x4
L = 9 + 16
L = 25
