Exercise 33 Page 279

The common difference is $- 3 .$

$A (n) = A (n - 1) - 3,$ $A (1) = 13$

Practice makes perfect

In order to write the recursive formula for the given sequence, we first need to find the common difference. We can do this by subtracting the first term of the sequence from the second term.

a_{2} - a_{1} = d \Rightarrow 10 - 13 = - 3
