They are a sequence of odd numbers. The next three in the sequence would be 17,19 & 21
15,30,45,60,75,90,105,120,135,150,165,180,,195,210,225,240,,255,270,285,300,.................................. and so on This is the sequence of numbers whose common difference is 15 and other numbers can be found by adding 15 to the previous number.
The numbers are increasing by 1,4,9,16,25,36.... which are square numbers so the next increase is 49. Making the next number in the sequence 141
Natural numbers only: Sequence length 1: 48. Sequence length 3: 15, 16, 17. If you allow for negative numbers, the following two are also possible: Sequence length 33: -14, -13, ... , 0, 1, ..., 15, 16, 17. Sequence length 97: -47, -46, ..., 47, 48. There is no other sequence with a total of 48 in the whole number domain. A solution would be: Let m be the first consecutive number. Hence: m + 1 = Second consecutive no. m + 2 = Third consecutive no. So the equation will be: 1st no. + 2nd no. + 3rd no = 48 m + (m + 1) + (m + 2) = 48 3m + 3 = 48 3m = 48 - 3 3m = 45 Dividing both sides by 3 gives: m = 15 by substitution: 15 + 1 = Second consecutive no. = 16 15 + 2 = Third consecutive no. = 17 Hence, the numbers are 15, 16 and 17. :-)
The sequence of differences between consecutive numbers is 9, 1, -20, 9, 1. If this continues then the next difference is -20 and therefore the seventh number is -5. (15 - 20).
eay its the fibbonacci code the answer is 15

15... you're dividing by 2 each time.
the sum of the first 15 prime numbers is 328 .
If numbers may be repeated . . . 36 If numbers may not be repeated . . . 30 If the sequence doesn't matter . . . 15
17
11, -10, 9
4 15 59 235 939 3755 15019 etcThe numbers increase by multiplying by 4, then subtracting 1 from the answer.This can be seen by visual comparison of the first three numbers. That the fourth number follows this sequence can be checked by using a calculator.So what is the next number?And, if you are really clever, what number comes before the 4?
The list comprises the first 4 numbers of the sequence: Un = -5n3 + 45n2 - 127n + 126 for n = 1, 2, 3, ...
Yes it is. In sequence from 1, the first 10 triangular numbers are... 1, 3, 6, 10, 15, 21, 28, 36, 45 & 55.

15 since you multiply by 3 then subtract 3 in sequence
