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> .
