You are bad at math. 1
the pattern appears to be add 5. subtract 4. add 3. subtract 2. so in theory it would be add 1. your answer would be 8
Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do.

Start with n, then you get; Add 17: n + 17 Double it: 2n + 34 Subtract 4: 2n + 30 Double it: 4n + 60 Add 20: 4n + 80 Divide by 4: n + 20 Subtract 20: n which is where you started.
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
An easy way to do this is to manipulate the original number and make sure to "undue" all the manipulations you did. For example: pick any number, add 3, subtract 2, subtract the number you started with, you have 1. Example explained: x + 3 - 2 - x = 1. More complex example: pick any number, multiply by 2, add 4, subtract 2, divide by 2, subtract 2, add 4, subtract the number you started with, you have 3. Explained: (((x * 2) + 4 - 2) / 2) - 2 + 4 - x = (2x + 2) / 2 + 2 = x + 3 - x = 3.

-4 take the number 1-9 and add 4 and you've got the answer
I like this one.... think of a number multiply by 2 add 12 subtract 4 divide by 2 subtract the number you thought of and the answer is 4 it always works its a mathematical certainty once you have the number 4 you can add subtract etc to your hearts content and make any new number provided you remember the answer yourself.

Subtract the numerator Subtract or add the numerator Subtract or add the numerator ex: 3/4-1/4=2/4 or 1/2 ex: 5/8 + 1/8= 6/8 or 3/4

Call the unknown number n. Then, from the problem statement, {4[(n + 7 - 2) - n]} - 2 = 18. This is always true because [(n + 7 - 2) - n] is simply 5.
IT looks like the operations is "add 4 subtract 3, add 5 subtract 2, add 6...". So the next step would be to subtract one. That would make the next number 11.
The number 4 is an integer (the Number 4.1 is a real number and not an integer) The number 2 is an integer (the number 2.9 is a real number and not an integer) 4-2 = 2 4+2 = 6 The above are examples of how the integers 4 and 2 can be added or subtracted.
You get 4 more than you started with.
