Answer:
22
Explanation:
We need to find what the sequence is increasing by each time
Take 2 adjacent numbers and subtract
18-14=4
14-10-4
10-6=4
Each time, we are increasing by 4
Since we are increasing by 4, we can add 4 on to the last number to find the next number in the sequence
18+4=22
So, the next number is 22, or choice C
