You will notice that in the series you describe, each number increases by an amount that is one more than the previous increase, so 7 + 1 = 8, 8 + 2 = 10, 10 + 3 = 13, 13 + 4 = 17. The next sequence will require adding 5 to 17, giving us 22.

There is no number pattern in 781013. But there is a number pattern in the numbers 7, 8, 10, 13. 7+1=8 8+2=10 10+3=13 Can you see the pattern? And the next number in this sequence would be ... ?

What would be the next number in this series 15 12 13 10 11 8?

The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.

Since each number is one less than the one before it, the next number would be 8.
This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
