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.
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
5 10 15 10 5
there is not much of a pattern there but i would say 45
15 (1 + 2 + 3 + 4 + 5).
What would be the next number in this series 15 12 13 10 11 8?
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
5 10 15 10 5
5
5
5
the answer should be 5
The next number is 30. The numbers are increasing in multiples of 5.
there is not much of a pattern there but i would say 45
The next number in the sequence would be 25.
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)
15 (1 + 2 + 3 + 4 + 5).
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
