Question

Which represents the recursive formula for the arithmetic sequence an = 7 - 3(n-1)?

A. az = 2 * 3
B. az = a1 - 3
C. az = a + 3
D. a3 = a2 - 7

Answer 1

The recursive formula for the arithmetic sequence an = 7 - 3(n-1) is represented by option B. az = a1 - 3.

Step-by-step explanation:

The recursive formula for the arithmetic sequence an = 7 - 3(n-1) is represented by option B. az = a1 - 3.

To determine the recursive formula, we need to identify the relationship between consecutive terms in the sequence. In this case, each term (an) is obtained by subtracting 3 times the previous term (an-1) from 7. Therefore, the recursive formula is az = a1 - 3
