Attempt following question by selecting a choice to answer.
D
Write a rule to describe the sequence
15, 12, 9, . . .DD DDA.
DStart with 15, and add 3 repeatedly
B.
DStart with 15, and add - 4 repeatedly
C.
DStart with 15, and add - 3 repeatedly
D.
DStart with 15, and add 4 repeatedly
D
C
Step 1: Observing the sequence the common difference between any two consecutive terms in the sequence is 3.[15 - 12 = 12 - 9 = 3.]
Step 2: Add -3 to each term of the sequence to get the next term.
Step 3: The sequence can be written as 15, (15 + (-3)), (12 + (-3)), (9 + (-3)), (6 + (-3)), . . .
Step 4: The rule is, start with 15, and add -3 repeatedly.
