To find the pattern, simply look for the difference in the first two numbers, then the following pair of numbers, etc.
2 9 5 13 10 19 17
2 + 7 = 9
9 - 4 = 5
5 + 8 = 13
13 - 3 = 10
10 + 9 = 19
19 - 2 = 17
The pattern is +7, -4, +8, -3, +9, -2...
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 ... ?
The next number in the sequence is 27.
20
31
10 (between 7 and 13)
The next number in the sequence is 122. The pattern involves adding increasing increments to each number in the sequence: +14, +10, +11, +13.
Since the terms of the given sequence differ by different numbers, then the terms would start a new pattern, so that the other term of the sequence is 23.16 26 21 13 23 18 10...
48 does not belong. The pattern is (times 2) then (plus 3). The last number should be 58.
22
The pattern is plus 7. So the next number used to be 1.
that best completes the sequence 2 9 5 13 10 19 17 is 27.
Arithmetic- the number increases by 10 every term.
