Find the difference and the next three terms - 10 - 20 - 30

- 40, - 50, - 60

Step-by-step explanation:

Note the common difference d between consecutive terms of the sequence.

- 20 - ( - 10) = - 20 + 10 = - 10

- 30 - ( - 20) = - 30 + 20 = - 10

Thus the difference d = - 10

To obtain a term in the sequence subtract 10 from the previous term

- 30 - 10 = - 40

- 40 - 10 = - 50

- 50 - 10 = - 60

The next 3 terms are - 40, - 50, - 60

The difference is 10, and the next three would be - 40 - 50 - 60
