Question

In the sequence 5, 8, 11, 14, ... the value of the common difference, d, is:

Answer 1

Answer: 3

Step-by-step explanation: The way I like to do this problem is work backwards. So, starting at 14, we subtract the previous term which is 11 to get 3. In the same way, 11 - 8 is 3, and 8 - 5 is 3. Since we end up with as our result each time, that's the common difference or the number we are repeatedly adding to get from one term to the next.

Answer 2

3

Explanation:

To find the common difference take the second term and subtract the first term

8-5 = 3

Check with the third term and subtract the second term

11-8 =3

The common difference is 3
