45.
These are the triangular numbers.
To find the next one, add one more than the previous difference:
1, 3 → difference is 2, so add 2 + 1 = 3 → 3 + 3 = 6
3, 6 → difference is 3, so add 3 + 1 = 4 → 6 + 4 = 10
etc
28, 36 → difference is 8, so add 8 + 1 = 9 → 36 + 9 = 45
The next number is -21
10 ten
10 4 3 11 15 9 8 16 20....
To find the next number in the series 16, 23, 19, 19, 22, 15, 25, we can look for a pattern among the numbers. The differences between consecutive numbers are +7, -4, 0, +3, -7, +10. The next difference appears to be -6, which would lead to the next number being 25 - 6 = 19. Therefore, the next number in the series is 19.
The next number in the series 7, 9, 11, 13, 15 is 17. This series is an arithmetic progression where each number increases by 2. Thus, adding 2 to the last number, 15, gives us 17.
The next number is -21
What would be the next number in this series 15 12 13 10 11 8?
the answer is 1
10
25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
10 ten

The Next NumberThe next number is 25 if you use the following pattern: 5, (the number 10), 15 (the first number +10), (the number 10), and the next number is the third number +10 or 25.or you could think of it this way:5, 10 (+5), 15 (+5), -5 (10)The pattern is +5, +5, -5, so the next number would be 15, the next 20, and the next 15.
