Exercise 16 Page 575

To write the formula for the $n th$ term, you need to know the common difference and the first term of the sequence.

$a_{32} = - 146$

Practice makes perfect

To begin, let's observe the given terms in the sequence to determine the value of the first term as well as the common difference.

9 \to - 5 4 \to - 5 - 1 \to - 5 - 6 \to - 5 - 11

We can use this information to write an equation for the

n th

term of the sequence.
