21:
(3)+3=(6)+4=(10)+5=(15)+6=(21)
They are: 0, -5, -10
5
To find the next number in the sequence 5, 15, 12, 24, 21, 21, 18, we can analyze the pattern. The differences between the numbers are: 10, -3, 12, -3, 0, -3. Following this pattern, the next difference would likely be 12, resulting in a next number of 18 + 12 = 30. Thus, the next number in the sequence is 30.
The next number is -21
the answer should be 5
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.
there is not much of a pattern there but i would say 45
What would be the next number in this series 15 12 13 10 11 8?
5 10 15 10 5
The rule is 5, 10, 15 and so the next number will be 20+31 = 51
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
They are: 0, -5, -10
