Step-by-step explanation:
step 1. 17/21 - 2/10 = x (in order to subtract you need a common denominator)
step 2. (17/21)(10/10) - (2/10)(21/21) = x
step 3. 170/210 - 42/210 = x
step 4. 128/210 = 64/105 = x
step 5. x = 64/105.
The next three terms are: 1/6 , 0 and -1/6
Step-by-step explanation:
Given sequence is:

First of all, we have to find the common difference

The common difference is -1/6
We can simply add -1/6 to the previous term to find the next terms so,
Adding -1/6 to 1/3

Hence,
The next three terms are: 1/6 , 0 and -1/6
