Since two people take both courses, we can subtract two from 7, 8, and 21, giving us 5, 6, and 19.
Add 5 and 6 together to get 11. Since eleven students are in those two groups, we can answer this. The answer will be 11/19.
Write the first few terms of the sequence.
f₁ = 6
f₂ = f₁ + 5 = 11
f₃ = f₂ + 5 = 16
f₄ = f₃ + 5 = 21
and so on
The sequence is
6, 11, 16, 21, ...,
This is an arithmetic sequence with a common difference of 5.
In function notation, the sequence is

This represents the equation of a straight line with n as the independent variable and f as the dependent variable.
The slope is 5.
A graph of the line is shown below.
Answer:
The sequence is

The slope is 5.
7 times 8 is 56
9 times 10 is 90
For number two it’s Milton,Laredo,France Because all you have to do is add the number of water and see which one is bigger and which one is smaller and put them in order
3 and 5 eights. All you have to do is subtract 5- 11/8 which is 1 and 3/8 which will give you 3 and 5 over eight as a answere
