Question

Find the next term of the arithmetic sequence:

3, 7, 11, 15, 19 …

• A. 23
• B. 24
• C. 22
• D. 25

Answer 1

The correct option is A 23

3, 7, 11, 15, 19 …

Let us calculate the difference between two consecutive terms.

7 - 3 = 4

11 - 7 = 4

15 - 11 = 4

19 - 15 = 4

We observe that the difference between two consecutive terms in the sequence is 4 and each term is 4 more than the previous term.

So, the next term = 19 + 4 = 23
