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 sequence is: +2, -1, -1, and every other number is written twice. The next few numbers are 3, 5, 4, 4, 3, 5, 5, 4, 3, 3… The sequence 3, 3, 5, 4, 4, 3, 5, 5, 4 keeps repeating.

the answer is 3
3. It is the number of letters in the names of positive integers in English.

The next number is 4. There is a sequence:Add 3, subtract 2, repeat
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.

I suggest 5, 4, 3, 6, 6 etc. This question is parochial since the sequence represents the number of letters in the names of integers in the English language.
