Question

Find the common difference of the arithmetic sequence. 4, 3 2/3, 3 1/3, 3, .... The common difference is ?

Answer 1

The numbers of the seria are:

`4,3\cdot(2)/(3),3\cdot(1)/(3),3`

so to find the diference we made the rest of two numbers so:

`3\cdot(2)/(3)-4=-(1)/(3)`

So the difference is -1/3
