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
Prime number sequence.
