Chapter SH, Problem 8.2.1EP

To determine

To calculate: To describe the sequence using words and symbols

Answer to Problem 8.2.1EP

Sequence is described by equation $t=25n$

Explanation of Solution

Given information:Sequence is $25,50,75,\mathrm{...}$

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 follow:

  $25,50,75,\mathrm{...}$

Here, $25$ is the term and its term number is $1$ . Each term of sequence is multiple of $25$

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

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

  $t=25n$

In words, term is twenty five times the term number.

Conclusion:

Hence, sequence is described by equation $t=25n$
