Determine if each sequence is an arithmetic sequence. If yes, find the common difference.
1. 10,12,15,19,…
2. If there is, what is the common difference?

Respuesta :

Answer: Yes, add one more each time you add

Step-by-step explanation:

No, the sequence is not arithmetic.

The difference between 10 and 12 is 2.
The difference between 12 and 15 is 3.
The numbers increase by different amounts each time, not by a constant amount, thus the sequence is not arithmetic.
