3968. The formula is the starting number squared, minus 1 (2*2-1=3...3*3-1=8....8*8-1=63..... 63*63-1=3968)

2 Add 1 to the number and then take the square root. 3968 + 1 = 3969 : √3969 = 63 63 + 1 = 64 : √64 = 8 8 + 1 = 9 : √9 = 3 3 + 1 = 4 : √4 = 2.
2 because sqrt(n+1) is the series.
2^2=4, 4 - 1=3, 3^2 = 9, 9 - 1= 8, 8^2= 64, 64 - 1= 63. So its the first number squared, then subtracted by 1, then that number is squared, then subtracted by 1, etc.

2 because sqrt(n+1) is the series.
(1) Take the difference of the two previous numbers in sequence (2) Add 4 to this difference. (3) Take the number from step #2 and add it to the previous number in the sequence. For example, to find the next number in the sequence: (1) 121 - 90 = 31 (2) 31 + 4 = 35 (3) 121 + 35 = 156
2^2=4, 4 - 1=3, 3^2 = 9, 9 - 1= 8, 8^2= 64, 64 - 1= 63. So its the first number squared, then subtracted by 1, then that number is squared, then subtracted by 1, etc.
-2 is a single number. A single number is not sufficient to define a sequence.
It is 214. The rule used is Un = (23n3 - 132n2 + 238n - 123)/3 for n = 1, 2, 3, ...
No. 63 is an odd number.
To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96
The answer would be 31, 62, 63, 126. HOWEVER the number 8 in the original series you supplied is inaccurate and should be removed.The sequence is to take first number and add one. The result is the second number. Take the second number and multiply by two. The result is the next number. Repeat these steps to complete the sequence.2 (+1) = 3 (*2) = 6(+1) = 7 (*2) = 14(+1) = 15 (*2) = 30 (+1) = 31(*2) = 62 (+1) = 63 (*2) = 126 ...
