F(n)=n^3+2 maybe, so 127
yeah, i had the same idea. 127.
These "guess the polynomial" questions don't seem to really fit the intent of this site. These should be puzzles that make one think, not simple math problems. But I'll say that at least you gave enough numbers this time to narrow it down to just a few equations, x^3+2 being the simplest.
I've just had another idea: 119 works, too. 3 plus the 4th prime number (7) is 10, plus the 8th prime number (19) is 29, plus the 12th prime number (37) is 66, so plus the 16th prime number (53) would be 119.
I have no plausible explanation for why one should start with 3 rather than 1, though.
what about 119? The difference are 7, 19, 37, ... 4th, 8th, 12th, prime number, would the next be 16th being 53 + 66 = 119? then the 20th for 190 (119 + 71). A theory. Starting with 3 might be simply for this particular question? Sure, that sounds plausible?
these are the 2 i found
127 = F(n)=n^3+2
119 = 3 plus the 4th prime number (7) is 10, plus the 8th prime number (19) is 29, plus the 12th prime number (37) is 66, so plus the 16th prime number (53) would be 119.
There are actually quite a few answers. Using Excell to do a linear series you get 79. 127 is the simplest answer, and 119 is another answer.
I'll try to post harder puzzles if you really want me to.
Mwoohahahaha!
ok again, this is a series of psychological numbers that any average human could create a working factorization of all of the numbers
So... No One else got 61?? Ouch... Clearly I don't know what I'm doing... >.>
