The pattern goes like this , times 4 the original number, then as the sequences moves on, subtract (-1, -2,-3,-4...and so on as the sequence goes on).

For instance 26 *4 =104

and this is the third sequence (the original number being composted). 

Therefore, we do the fourth one by 101*4-4= 400

Now we do the fifth one, by 400*4 -5 = 1595

The correct answer is 1595
