Step-by-step explanation:
-2,0,2,4,6
To get from the first term to the second term, we add 2
To get from the second term to the third term, we add 2
To get from the third term to the fourth term, we add 2
The common difference is 2
This is an arithmetic sequence.
There is no single number we can multiply by to move from once term to the next, so it is not a geometric sequence.
yes it is .....,...............reflex angle
Answer:
After 4 days, the number of people attending both conferences be the same.
Step-by-step explanation:
We are given the following in the question:
Maths conference:
Number of people already signed = 7

History conference:
Number of people already signed =11
Number of people who sign up each day = 1
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

Both conference will have same number of people when

Thus, after 4 days, the number of people attending both conferences be the same.
