The next number is 16. Counting forward from the first 1 - every other number is an increment of 1. From the second 1 - every other number is the square of the number it follows. Therefore the next number is 16, then 5, then 25, then 6... and so on...
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
4.
The third number is 2 -- the first number is 1, second is 1, next is 1+1=2, then 1+2=3, 2+5=5 etc.
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 answer is 8 because 1+1=2, 1+2=3, 2+3=5,and 3+5=8.
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 next number is 61. The rule is Un = (33n4 - 394n3 + 1599n2 - 2510n + 1296)/24 for n = 1, 2, 3, ...
The third number is 2 -- the first number is 1, second is 1, next is 1+1=2, then 1+2=3, 2+5=5 etc.
