Answer: 453 The number given can be seen as a sequence of 63 60 56 51. Taking these as separate numbers: 60 is 63 minus 3 56 is 60 minus 4 51 is 56 minus 5 the numbers decrease by the (difference between the last two numbers plus 1) So, 51 minus 6 gives 45 and 45 minus 7 gives 38 The next three numbers are, therefore, 453
4
the answer is three
next to one and three
The number 9: factors are 9, 3, and 1.
The next square number after ten (which is not a square number) is 16. Sixteen has five factors.
Each number is three times the previous number.
Each number is three times the previous number.
The pattern is add three and then multiply by three. The next number is 174.
Each number in the sequence is 8 times the preceeding number so the next three numbers would be... 204.8, 1638.4 and 13107.2
Assuming you start with 3/8 and count by 3/8, the next number would be 6/8 = 3/4.
One number, such as 23266992 does not for a sequence.
Together, they are called "thirty-three".
