First we have to figure out what the next 2 terms are, ya reckon ?

Look at the terms we have:

From the 1st to the 2nd term . . . add <em>2</em>
From the 2nd to the 3rd term. . . add <em>4</em>
From the 3rd to the 4th term . . . add <em>6</em>
From the 4th to the 5th term . . . add <em>8</em>

So there's the pattern we want.

To get the next term,          we add  <em>10</em>  to 17, and get  27.
And for the one after that, we add  <em>12</em>  to 27, and get 39 .

To answer the question, the sum of (27 + 39) is<em>  <u>66</u></em> .

Which exponential function has an initial value of 2?<br><br> f(x) = 2(3x)<br><br> f(x) = 3(2x)
Sidana [21]
<span>f(x) = 2(3x)
Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses. 
Exponential growth formula.
</span>y=a(1+r)^{x}
<span>a represents the initial value.</span>
