Step 1:
I'll solve this step by step using the specified LaTeX formatting guidelines:

Step 2:
: List out all numbers between 130 and 150

The numbers are: 131, 133, 137, 139, 141, 143, 147, 149

Step 3:
: Check each number for primality

- A prime number is only divisible by 1 and itself - I'll systematically check divisibility for each number

Step 4:
: Verify primality

- 147: Not prime ($$147 = 3 \times 49$$)
- 131: Prime (no divisors other than 1 and 131) - 137: Prime (no divisors other than 1 and 137) - 139: Prime (no divisors other than 1 and 139) - 149: Prime (no divisors other than 1 and 149)

Step 5:
: Count prime numbers

The prime numbers are: 131, 137, 139, 149

Final Answer

4 prime numbers exist between 130 and 150.
