Exercise 85 Page 478

Start by identifying the starting value and the common ratio of the geometric sequence.

a_1=10; a_n=a_(n-1) * 1/10

Practice makes perfect

We want to write the recursive formula for the given geometric sequence. Let's identify the starting value a_1 and the common ratio r.

The starting value is a_1= 10 and the ratio between the consecutive terms is 110. Therefore, the common ratio of the sequence is r= 110. Let's use this information to write the recursive formula for our geometric sequence. General Form:& a_1= a; a_n=a_(n-1) * r Given sequence:& a_1= 10; a_n=a_(n-1) * 1/10
