Final answer:
The common difference, d, of the sequence -15, -4, 18, 29 is 11.
Step-by-step explanation:
The common difference, d, of a sequence is the constant difference between any two consecutive terms. To find the common difference in the sequence -15, -4, 18, 29, we subtract each term from its previous term:
- -4 - (-15) = 11
- 18 - (-4) = 22
- 29 - 18 = 11
The common difference, d, in this sequence is 11.
