Represent the arithmetic series using the recursive formula 94, 87, 80, 73,
Rama09 [41]

Answer:

a_1 = 94 \\ a_n = a_ {n - 1}  - 7

Step-by-step explanation:

The given arithmetic sequence is 94, 87, 80, 73,...

The first term is

a_1=94

The common difference is

d = 87 - 94

d =  - 7

The recursive formula is given by:

a_n = a_ {n - 1} + d

We substitute the common difference to obtain:

a_n = a_ {n - 1}  - 7
