Answer :
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 2
From the 2nd to the 3rd term. . . add 4
From the 3rd to the 4th term . . . add 6
From the 4th to the 5th term . . . add 8
So there's the pattern we want.
To get the next term, we add 10 to 17, and get 27.
And for the one after that, we add 12 to 27, and get 39 .
To answer the question, the sum of (27 + 39) is 66 .
