what are the next three terms in the sequence? -1,9,19,29, ...
10 is added to the previous number to get the next one in the sequence.
so the next one would be 38?
No.
To find the next three terms in the sequence -1, 9, 19, 29, ... , you need to determine the pattern of the sequence. One way to find this pattern is to examine the differences between consecutive terms.
Let's calculate the differences between each term:
9 - (-1) = 10
19 - 9 = 10
29 - 19 = 10
From this, we can observe that the difference between each term is constant and equal to 10. This suggests that the sequence is an arithmetic sequence with a common difference of 10.
To find the next terms, we need to add 10 to the last term of the sequence:
The last term is 29, so the next term would be 29 + 10 = 39.
The term after that would be 39 + 10 = 49.
The term after that would be 49 + 10 = 59.
Therefore, the next three terms in the sequence are 39, 49, and 59.
