Answer:
A natural number is a number that occurs commonly and obviously in nature. As such, it is a whole, non-negative number.
Step-by-step explanation:
Answer:
1. In order for Pattern B to be linear, the common difference of the number of dots between each step should be constant. As it is not constant, the pattern is not linear.
2. In order for Pattern B to be exponential, the common ratio of the number of dots between each step should be constant. As it is not constant, the pattern is not exponential.
3. In order for Pattern B to be quadratic, its sequence of second differences must be constant.
First differences:

Second differences:

Therefore, as the sequence of second difference is constant, the patten is quadratic.
The function for pattern B is: 
(where x is the step number)
Answer:
1.) 5
2.) 14
Step-by-step explanation:
As given,
the expression - 3x + 2
1.)
Evaluate the expression when x is 1
⇒ 3x + 2 = 3(1) + 2 = 3+2 = 5
2.)
Evaluate the expression when x is 4
⇒ 3x + 2 = 3(4) + 2 = 12+2 = 14
Hey You!
3,000 * 30% = 900
So, Tom spends $900 on his monthly rent.
Peter: x
Arasoo: x+4
Ali: x-2
4+x+x+x-2=47
2+3x=47
3x=45
x=15
Peter: 15
Arasoo: 15+4= 19
Ali: 15-2 = 13
