One possible (though simple) solution is:
1 1 2 3 3 4 5 5 6 7 7 8...
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
The next number is 4, followed by -2
Correct. For example: 1 + 1 = 2 2 + 1 = 3 3 + 1 = 4
The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
4.
If you fit the following cubic t(n) = (-n3 + 9n2 - 20n + 18)/3 where n = 1, 2, 3, ... then the next number is t(6) = 1
8 -1 then +3
The next number is 1004.The rule is Un = (-73n4 + 893n3 - 3803n2 + 6520n - 3504)/3 for n = 1, 2, 3, ...The next number is 1004.The rule is Un = (-73n4 + 893n3 - 3803n2 + 6520n - 3504)/3 for n = 1, 2, 3, ...The next number is 1004.The rule is Un = (-73n4 + 893n3 - 3803n2 + 6520n - 3504)/3 for n = 1, 2, 3, ...The next number is 1004.The rule is Un = (-73n4 + 893n3 - 3803n2 + 6520n - 3504)/3 for n = 1, 2, 3, ...
The sequence provided is the Fibonacci sequence, where each number is the sum of the two preceding ones. In this case, after 1, 1, 2, 3, and 5, the next number is 3 + 5, which equals 8. Therefore, the next logical number in the sequence is 8.
The answer is 8 because 1+1=2, 1+2=3, 2+3=5,and 3+5=8.
The next number is 61. The rule is Un = (33n4 - 394n3 + 1599n2 - 2510n + 1296)/24 for n = 1, 2, 3, ...
