Answer:
The first four terms of the above sequence are 1, 6, 11, 16.
Step-by-step explanation:
A sequence is defined by the function f(n)=f(n-1)+5.
Where n represents the number of the term for n>1
First Put n = 2
f(2)=f(2-1)+5.
= f (1) + 5
= -4 + 5
= 1
Second Put n = 3
f(3)=f(3-1)+5.
= f (2) + 5
= 1 + 5
= 6
Third Put n = 4
f(4)=f(4-1)+5.
= f (3) + 5
= 6+ 5
= 11
Second Put n = 5
f(5)=f(5-1)+5.
= f (4) + 5
= 11 + 5
= 16
Therefore the first four terms of the above sequence are 1, 6, 11, 16.
Answer:
The next term is 13.
Step-by-step explanation:
Looking at the previous numbers...
for -7 to get to -3, you have to add 4, and for -3 to get to 1 you have to add 4.... and so on. So in order to find the next number, add 4 to 9, and which you get 13.
The answer would look something like this:

There could also have a simplified version.

Answer: 1 pound of cheese cost $4.2
Step-by-step explanation:
Nola purchased 2.5 pounds of cheese for 10. $50
Her mother purchased 3 pounds of the same cheese for $12.60
If the cost of the cheese varies directly with the number of pounds purchased, it means that the higher the pounds of cheese purchased, the higher the cost
To determine the the cost of 1 pound of cheese, we wound divide the the cheese by the number of pounds bought.
It becomes 10.5/2.5 = 4.2
