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.
The number sequence appears to be alternating between multiplying by 2 and subtracting 1. Starting with 2, we get 22 = 4, then 4-1 = 3, then 33 = 9, then 9-1 = 8, then 88 = 64, and finally 64-1 = 63. Therefore, the next number in the sequence should be 6363 = 3969.

63
63 is NOT an even number, it is an an odd number, because it does NOT end in 0,2,4,6,8. Therefore it will NOT divide by '2'. So try the next prime number , which is '3' 3)63 = 3)21 = 7)7 = 1 When reduced to '1' , all the primes are factors. Hence 3 x 3 x 7 = 3^(2) x 7^(1) = 3^(2) x 7 Done!!!!!
It is 214. The rule used is Un = (23n3 - 132n2 + 238n - 123)/3 for n = 1, 2, 3, ...
No. 63 is a composite number with two unique prime factors. 63 = 3 * 3 * 7

63 / 3 = 21The middle number is 21The odd numbers next to 21 are 19 and 2319 + 21 + 23 = 63
Prime Factor tree of 63. We note that '63' is an odd number , because it does NOT end in 0,2,4,6,8 So it will not divide by ;2 So we try the next prime number, which is '3' 3)63 = 21 Keep on dividing by '3' until it will not divide any further by '3' 3)21 = 7 Since '3' will not divide into '7' and '7' is a prime number, divide '7' into itself , to reduce to '1' 7)7 = 1 So the prime factor tree/stepladder of '63' is 3,3,7. This can be expressed as 3^(2) x 7^(1) = 3^(2) x 7 .
It is: 23 and 63/1000
prime factorizing, 63 = 3*3*7 and 28 = 2*2*7, so the answer is 7.
63 = 7*9= 7*3*3= 7* (3)^2
