Question

5,9,14,20 is an arithmetic sequence
yes or no

Answer 1

No, the sequence 5, 9, 14, 20 is not an arithmetic sequence. In an arithmetic sequence, the difference between consecutive terms must be constant.

Let's find the differences between the terms:

- 9 - 5 = 4
- 14 - 9 = 5
- 20 - 14 = 6

Since the differences (4, 5, 6) are not constant, the sequence is not arithmetic.
