What is the next number in this progression?
42, 51, 59, 68, 77, 86, ?
94

I am guessing it should be 95 based on the obvious choice of adding 9 to each number. But then again, the second and third number are only 8 apart. I thought it had something to do with the sum of the digits (6, 6, 14, 14, 14, 14). 95 still works with that as well but doesn't make sense for the progression. I may be just taking the bait on this one and looking for the obvious and missing the easy answer.
11
Hint:
Scott Zelenak probably knows the answer right off the top of his head. The answer is 96.
The progression is the street numbers of the NYC subway stops north along the east side of Central Park...
Yea, I know, cheap shot...it took me a while, too.

I was guessing p5 also for the same and another reason also.
86 is th reverse of 68 prior to the 77 and then the next reverse going back is 95 from the 59.
Numbers are funny.
Our son just turned 9 and I showed him that 9 was such a great #.
I showed him how to take any number and add its column numbers and subtract from ther original number and always the answer is 9.
I was going to guess "Netflix" and move on to the bonus round.
I'm going to go with 96. The progression is 9,8,9,9,9,10.
That's the same, as I have scribbled on my notepad.

9 is an awesome number. If you take the sum of its multiple, it will always equal nine. i.e. 9 * 3 = 27. 2 + 7 = 9. I could go on.. but this was the easiest to explain.
42 4+2=6
51 5+1=6
59 5+9=14
77 7+7=14
86 8+6=14
6+6+14+14+14=54
54 5+4=9
9 is what separates all the original numbers;
54 identifies and breaks the progression, but 4+5 also = 9;
45+6=51 and we start all over;
45+14=59 and we start all over;
surely this is a paradox without end!
96
96 works.
9 is the number that separates all the original numbers;
6 is the sum of the first two original numbers;
9+6=14
14 is the sum of the remaining numbers.
^5 Tim!
I just asked Jimi Hendrix "What if 6 was 9"? He told me to stand on my head and figure it out for myself.;-)
