Answer:
13
Step-by-step explanation:
This problem is a type of puzzle called a Number Pattern. Number patterns always follow a <em>specific pattern</em>. In this case, <u><em>its +9, -3.</em></u>
The <em>first number </em>in this pattern is 1.
The <em>second number</em> in this pattern is 10.
<u><em>That is an increase of +9.</em></u>
The <em>third number</em> in this pattern is 7
<u><em>That is a decrease of -3.</em></u>
The <em>fourth number</em> in this pattern is 16.
<u><em>That is an increase of +9.</em></u>
Therefore, we can conclude that the <em>next number</em> will have to be a <u><em>decrease</em></u> of -3.
<u><em>16 - 3 = 13</em></u>
