Describe the relationship between the terms in each arithmetic sequence. Then write the next three terms in the sequence.

0.4, 0.8, 1.2, 1.6, ...

add 0.4

No

To describe the relationship between the terms in an arithmetic sequence, you need to look for a common difference.

In this sequence, if we subtract each term from its preceding term, we can observe that the common difference is 0.4.

So, the next term in the sequence would be obtained by adding the common difference (0.4) to the last term:
1.6 + 0.4 = 2.0

To find the next three terms, we repeat the process:
2.0 + 0.4 = 2.4
2.4 + 0.4 = 2.8
2.8 + 0.4 = 3.2

Therefore, the next three terms in the sequence are 2.0, 2.4, and 2.8.
