It can be hard to answer questions of this type based on only three examples. However, that does happen to be the start of the sequence called the "triangular numbers" ... that is, those quantities that can be arranged in an equilateral triangle (like Bowling pins or billiard balls). The next number in the triangular sequence is 10 (followed by 15, 21, 28, etc).
In a number series, you must figure out the "pattern" in order to say what will be the next number. For example, in each of the following number series, say what is the pattern, and what is the next number. 1. 1 3 5 7 Answer: The pattern is to increase the previous number by 2, and the next number is 9. 2. 3 10 31 94 Answer: The pattern is to multiply the previous number by 3, then add 1, and the next number is 283. 3. 100 10 1 0.1 Answer: The pattern is to divide the previous number by 10, and the next number is 0.01.
The pattern is +4, 2x, +4, 2x, and so on. The next number is 32.
The pattern is that each number equals to one tenth of the number before it. The number that will come next will be one tenth of 10, which is 1.

The next number is 7 then 4, alternately counting down from 10 and up from 1.

7 is the next number in the pattern
n^2 (figure number squared)
The pattern is +4, 2x, +4, 2x, and so on. The next number is 32.
3 4 5 6 The next number is 1 plus the previous number So the pattern rule is the next number is n + 1
The pattern is plus 7. So the next number used to be 1.

this cannot be solved, as there is no pattern...

If you mean: 1 1 2 3 5 8 13 21 then the next number is 13+21 = 34
The pattern is that each number equals to one tenth of the number before it. The number that will come next will be one tenth of 10, which is 1.
