Determine the recursive formula
The given sequence shows arithmetic progression (AP).
First, we calculate the common difference (d):


The recursive formula of an AP is determined using:
where 
Substitute 3 for d
where 
4.57 rounded to the nearest whole number is 5
Answer:
yes I think I'm new to this but I think that's a yes
Answer:
Step-by-step explanation:
mean is found by adding the numbers and dividing the sum by the number while the median is the middle value of the list ordered in an ascending order
Answer:
B
Step-by-step explanation:
Well since it is arthimetic sequence we know the formula
We know d is difference between second term and first so it will be -5- (-12)= -5+12= 7

the domain of this is 1,2,3,4.......
range is -12,-5,2,9.......
Therefore answer is B.
