Answer:
a) The table of values represents the ordered pairs formed by the elements of the sequence (
) (range) and their respective indexes (
) (domain):
![a_{i}](https://tex.z-dn.net/?f=a_%7Bi%7D)
1 6
2 11
3 16
4 21
5 26
b) The algebraic expression for the general term of the sequence is
.
c) The 25th term in the sequence is 126.
Step-by-step explanation:
a) Make a table of values for the sequence 6, 11, 16, 21, 26, ...
The table of values represents the ordered pairs formed by the elements of the sequence (
) (range) and their respective indexes (
) (domain):
![a_{i}](https://tex.z-dn.net/?f=a_%7Bi%7D)
1 6
2 11
3 16
4 21
5 26
b) Based on the table of values, we notice a constant difference between two consecutive elements of the sequence, a characteristic of arithmetic series, whose form is:
(1)
Where:
- First element of the sequence.
- Arithmetic difference.
- Index.
If we know that
and
, then the algebraic expression for the general term of the sequence is:
![a(i) = 6 + 5\cdot (i - 1)](https://tex.z-dn.net/?f=a%28i%29%20%3D%206%20%2B%205%5Ccdot%20%28i%20-%201%29)
c) If we know that
and
, then the 25th term in the sequence is:
![a(25) = 6 + 5\cdot (25 - 1)](https://tex.z-dn.net/?f=a%2825%29%20%3D%206%20%2B%205%5Ccdot%20%2825%20-%201%29)
![a(25) = 126](https://tex.z-dn.net/?f=a%2825%29%20%3D%20126)
The 25th term in the sequence is 126.
7:14 or simplified 1:2 (use simplified)
Find total amount of fruit by adding
4+7+3=14
7 pears to 14 total fruits in ratio form is 7:14 which simplifies to 1:2
