6. Look for a pattern. What are the next two numbers in this pattern?
1,3,7, 13, 21, 31, 43, 57,

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.
