Is 10,15,21,28 arithmetic? Common difference
The given sequence 10, 15, 21, 28 is arithmetic because there is a common difference between each pair of consecutive terms. To find the common difference, we can subtract each term from the previous term:
The difference between 15 and 10 is 15 - 10 = 5.
The difference between 21 and 15 is 21 - 15 = 6.
The difference between 28 and 21 is 28 - 21 = 7.
Since the differences are not equal, the common difference is not the same throughout the sequence.
To determine if the given sequence 10, 15, 21, 28 is arithmetic, we need to check if there is a common difference between consecutive terms.
To find the common difference, we subtract each term from the previous term. Let's go through the steps:
15 - 10 = 5
21 - 15 = 6
28 - 21 = 7
The differences between consecutive terms are not the same. The differences are 5, 6, and 7, which means there is no common difference. Hence, the given sequence 10, 15, 21, 28 is not arithmetic.
