<p>89, 88, 85, 78, 63, ?</p>

<p>The series follows the following pattern:</p>

<p>⇒ 89 - 88 = 1</p>

<p>⇒ 88 - 85 = 3</p>

<p>⇒ 85 - 78 = 7</p>

<p>⇒ 78 - 63 = 15</p>

<p>Now taking the difference of the differences</p>

<p>⇒ 3 - 1 = 2 ⇔ 2<sup>1</sup></p>

<p>⇒ 7 - 3 = 4 ⇔ 2<sup>2</sup></p>

<p>⇒ 15 - 7 = 8 ⇔ 2<sup>3</sup></p>

<p>Next would be 2<sup>4</sup></p>

<p>⇒ 15 + 16 = 31</p>

<p>⇒ 63 - 31 = 32</p>
