Question

Which of the following sequences of numbers are arranged correctly from the smallest to the greatest?

$\begin{array}{cc}2,9,25,29,19& 5,10,15,19,29\\ \text{Sequence 1}& \text{Sequence 2}\end{array}$

• A. Both the sequences
• B. None of the sequences
• C. Sequence 1
• D. Sequence 2

Answer 1

The correct option is D Sequence 2

Sequence 1:
$2$ is the smallest.
$9$ is greater than $2$ but smaller than $25,29,$ and $19.$
$25$ is greater than $9$ but smaller than $29$.
$29$ is the greatest number of the sequence.
$19$ is greater than both $2$ and $9$ but smaller than both $25$ and $29.$
So, $19$ should be placed after $2$ and $9,$ but before $25$ and $29.$

Therefore, Sequence $1$ is not correctly arranged.

Sequence 2:
$5$ is the smallest.
$10$ is greater than $5$ but smaller than all the other numbers of the sequence.
$15$ is greater than both $5$ and $10$ but smaller than both $19$ and $29.$
$19$ is greater than all the other numbers except $29$.
$29$ is the greatest number in the sequence.
Therefore, we can conclude that Sequence $2$ is correctly arranged from smallest to greatest.

Hence, Option B is correct.
