Question

Find the common difference of the arithmetic sequence2, 1 8/9, 1 7/9, 1 2/3,...

Answer 1

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

`1(8)/(9)=1+(8)/(9)=(9+8)/(9)=(17)/(9)`

2 - 1 8/9

`2\text{ - }(17)/(9)=(18-17)/(9)=(1)/(9)`

The answer is:

1 / 9
