Answer:
The next number is 73.
Explanation:
The rule is +2, +4, +6, +8, +10, +12, +14, +16, etc.
Each time you want to find the next number in the pattern, just increase your addend by two.
43+14 = 57
Now, I will increase my addend by two.
So, it would be 57+16 = 73.
Therefore, 73 is the next number in the pattern.
