What is the next number in this sequence? 3,5,7,15,27,49,?

Answer 1

Miquel Andreu Fuster Sancho please don't write codes for them, in most cases let the user show there try of the code since we are all here to learn, and we don't do there assignments for them

Answer 2

Denise Rossberg you are right, I should have looked further at the list. It's my bad 🤔🙄😌🤗

Answer 3

A 64 bits machine can compute only the 72 first numbers of the sequence.

Answer 4

✳AsterisK✳ he is doing his code in python, that is kindly different from C. Anyway, he already had the algorithm, only he can't find a way to translate it to python. While the solution is not in that language I think it is good to publish alternatives.

Answer 5

3+5+7=15
5+7+15=27
7+15+27=49
15+27+49=91

Answer 6

Those are prime numbers if I am not wrong

Answer 7

Yeah, that one is easy.

Answer 8

OK Miquel Andreu Fuster Sancho

Only 3 5 and 7 are primes.

15 is not prime: 15/3 = 5
27 is not prime 27/9 = 3
49 is not prime 49/7 = 7

Answer 13

R u sure about 49? Is it maybe 39?

Answer 14

Okay, then the next number should be 41.

Answer 15

Why?

Answer 16

Sorry, s = 3,5,7,15,27,49,...

Answer 17

3+5+7 = 15
15+7-5 =17
7+15+17=39
39+17-15=41

Not my favorite sequence but the only one that fits.

Edit: Well, it would have worked...

Answer 18

15=3+5+7
27=5+7+15
49=7+15+27
....

Answer 19
