Chapter 8, Problem 6MCQ

To determine

To calculate: To describe the sequence using words and symbols

Answer to Problem 6MCQ

Sequence is described by equation is $t=9n$

Explanation of Solution

Given information: Sequence is $9,18,27,\mathrm{36...}$

Formula Used:

Term: In a sequence, each number is referred to as a term

Term Number: In a sequence, the position of the given term is referred to as term number.

Calculation:

Sequence is given as

  $9,18,27,\mathrm{36...}$

Here, $9$ is the term and its term number is $1$ . Each term of sequence is multiple of $9$

Let term is denoted by $t$ and term number is denoted as $n$

Thus, the given sequence can be described in symbols as follows:

  $t=9n$

In words, term is $9$ times the term number.

Conclusion:

Hence, sequence is represent in symbols as $t=9n$
