Find the common difference in the arithmetic sequence 1,7,13,19?​

Sagot :

Answer:

6

Step-by-step explanation:

In order to find the common difference of the arithmetic sequence, we need to subtract the 2nd number to the 1st number so if we pick 2 pairs of numbers, we always get 6

Pairs of numbers: 1 and 7, 7 and 13, 13 and 19

7 - 1 = 6

13 - 7 = 6

19 - 13 = 6
