The answer is 5 only.
Well, in this type of question, we just simply need to find the value of n
4n + 6 > 22
4n > 22 - 6
4n > 16
n > 4
From the set, the only number that bigger than 4 is 5.
For proof:
- first, try to replace n with 4
4 (4) + 6 > 22
22 > 22 ..................................Wrong
- then we can try to replace n with a number that is bigger than 4
4(5) + 6 >22
26 > 22 ..................................Correct
