Answer: first option
Step-by-step explanation:
To form an arithmetic sequence, you have that for the sequence [tex]7,6k,22[/tex]:
[tex]6k-7=22-6k[/tex]
Therefore, to calculate the value of k to form an arithmetic sequence, you must solve for k, as following:
- Add like terms:
[tex]6k+6k=22+7\\12k=29[/tex]
- Divide both sides by 12. Then you obtain;
[tex]k=\frac{29}{12}[/tex]
Answer:
[tex]k=\frac{29}{12}[/tex]
Step-by-step explanation:
The given sequence is 7, 6k, 22.
For this to be an arithmetic sequence, there must be a common difference.
[tex]6k-7=22-6k[/tex]
Group similar terms;
[tex]6k+6k=22+7[/tex]
Simplify;
[tex]12k=29[/tex]
Divide by 12
[tex]k=\frac{29}{12}[/tex]
