Chapter 11.4, Problem 28WE

To determine

To calculate:

The series for the following condition:

The positive two digit integers ending in $2$

Answer to Problem 28WE

The sequence is defined as $12,22,32,42,52,62,72,82,92$

Explanation of Solution

Given information:

The positive two digit integers ending in $2$

Calculation:

Know that:

The positive two digit integers start from $10$ and ends $99$ . But need to define the series which ends in $2$ :

  $12,22,32,42,52,62,72,82,92$

So, here terms are considered as:

  $\begin{array}{l}{a}_1=12\\ a_2=22\\ a_3=32\\ a_4=42\\ a_5=52\\ a_6=62\\ a_7=72\\ a_8=82\\ a_9=92\end{array}$
