Step-by-step explanation:
First term(a) = 1
Common difference(d)=2-1=1
No.of term(n)=50
Sn=n÷2(n+1)=50÷2(50+1)=1275
Answer:
;
Step-by-step explanation:
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:
;
This look overly complicated I think it’s just 136 because 180 - 46 is 136
