Chapter 11.3, Problem 28PS

To determine

(a)

To find:

Whether the sequence $\frac{1}{10},\frac{1}{5},\frac{3}{10},\frac{2}{5},\frac{1}{2}\text{,}\mathrm{....}$ is arithmetic, geometric, Fibonacci, or none of these.

To determine

(b)

To give:

The first two terms, if Fibonacci, give $d$ if the sequence is arithmetic, give $r$ if geometric, and if none of these then state a pattern using own words for the sequence $\frac{1}{10},\frac{1}{5},\frac{3}{10},\frac{2}{5},\frac{1}{2}\text{,}\mathrm{....}$.

To determine

(c)

To find:

The next term of sequence $\frac{1}{10},\frac{1}{5},\frac{3}{10},\frac{2}{5},\frac{1}{2}\text{,}\mathrm{....}$.
