In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
2, 1 8/9, 1 7/9, 1 2/3
Step 02:
arithmetic sequence
1 8/9
[tex]1\frac{8}{9}=1+\frac{8}{9}=\frac{9+8}{9}=\frac{17}{9}[/tex]2 - 1 8/9
[tex]2\text{ - }\frac{17}{9}=\frac{18-17}{9}=\frac{1}{9}[/tex]The answer is:
1 / 9
