What are the next three terms in the sequence?

-1, 9, 19, 29, ...

38, 37, 32

40, 51, 62

39, 49, 59

38, 47, 56

38, 47, 56

To find the next three terms in the sequence -1, 9, 19, 29, ..., we need to identify the pattern or rule governing the sequence.

If we observe carefully, we can see that each term is obtained by adding 10 to the previous term.

Using this pattern, we can find the next three terms as follows:

The next term is obtained by adding 10 to the last term, which is 29. So, the next term is:
29 + 10 = 39.

The second next term is obtained by adding 10 to the previous term, which is 39. So, the second next term is:
39 + 10 = 49.

The third next term is obtained by adding 10 to the previous term, which is 49. So, the third next term is:
49 + 10 = 59.

Therefore, the next three terms in the sequence are: 39, 49, 59.
