From eye, either 14 or 17 look to be incorrect because the sequence seems to roughly double everywhere apart from there. Although, of course, there are many solutions where this isn't the case and since I haven't been able to spot a solution, take this with a pinch of salt.
I think the last one is the wrong number. What I did is:
- I doubled the 35 so: 35 + 35 = 70
then I get the number before 35 which is 17
and I add it to the 70 so: 35 + 35 = 70 + 17 = 87.
- Next is I doubled the 87 so: 87+87 = 174
then I get the number before 17 which is 14
and I add it to the 174 so: 87 + 87 = 174 + 14 = 188
- I repeated the flow on the last digit.
188 + 188 = 376 +87 = 463
463+463 = 926 + 35 = 961 and so on and so forth..
In short:
14 17 35 87 188 463 961 ...
BUT IT IS JUST A GUESS..not sure of the exact formula!
