There are infinitely many polynomials of order 5 that will give these as the first five numbers and any one of these could be "the" rule. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one. And each one of these polynomials will give a different number as the next.
So, any number that you choose can be the next number.
The simplest solution, based on a polynomial of order 4, is
U(n) = (7*n^4 - 98*n^3 + 497*n^2 - 1078*n + 840)/24.
The next number is 30+7 = 37.
The pattern is plus 7. So the next number used to be 1.
16.
7
47
12
it's a number
7
1+7=8 8-7=1 1+3=4 4+3=7 7-7=0 0+7=7 7-7=0 x=0+3 the next number is 3
7 is the next number in the pattern
The next number is 30+7 = 37.
Either 7, 2 or 27?
The next number is 10. The pattern is -7, -6, -5, -4.
The pattern is plus 7. So the next number used to be 1.
The next number in pattern is: 1 The next number in pattern is: 1 Reason: If you pick up the alternate number form left starting from second position then the sequence is: 7 4 2 1 ? Take the difference of two consecutive numbers in the above series 7-4 = 3 4-2=2 2-1=1 1-1=0 So the answer is: 1
prime numbers - next number is 13
It looks to me like 3 may be the next number since it goes +7, -7, +3, +3, -7, +7, -7, then maybe +3, +3 again. Anybody else see something different?
