An arithmetic sequence with a common difference of 4 include the following: D. 5,9,13, 17, 21, ...

In Mathematics and Euclidean Geometry, the nth term of an arithmetic sequence can be calculated by using this equation:


a_n=a_1+(n-1)d

Where:

  • d represents the common difference.

  • a_1 represents the first term of an arithmetic sequence.
  • n represents the total number of terms.

Next, we would write an explicit equation for the sequence by using the arithmetic sequence formula;

Common difference, d = succeding term - preceeding term

Common difference, d = 9 - 5 = 13 - 9 = 17 - 13 = 21 - 17

Common difference, d = 4.
