Find the next term of the arithmetic sequence: 3, 7, 11, 15, 19 … A....

Let us calculate the difference between two consecutive terms.
7 - 3 = 4
11 - 7 = 4
15 - 11 = 4
19 - 15 = 4
The sequence's difference between any two consecutive terms is 4, and each term is 4 more than the one before it.
So, the next term = 19 + 4 = 23
