66 is the answer its to simple because it is muiltipled odd numbers
66 is the correct answer but I could not get your logic.
You can check out my logical reasoning used to solve this puzzle in this post.
For those puzzled by the sequence, notice the SUM goes up by 9, then 13, than 17...or 4 more each time. So the next sum should go up by 21 (17+4), or 21 added to the last sum which was 35. When you find out the differences, its called first difference. Then when you find out how much the differences are going up by, thats the 2nd difference. The 2nd difference is 4, consistently, which tells you the sequence is a parabola or x^2. The general formula for a parabola is y=ax^2 + bx + c, and to find a, b and c, you use the various info provided. When x=1, y is 6, so 6=a + b +c, when x=2, y=15, so 15=4a+ 2b + c, and when x=3, y is 28, so 28 =9a+ 3b +c...3 missing variables, 3 equations, you discover y=2x^2+3x+1, which factors into y = (2x+1)(x+1). There answer uses the sequence formula
