Maritza remembers her pin because it is the product of consecutive prime numbers that is between 1000 and 1500. what is her pin

Find the pin number of Maritza which is between 1000 and 1500.
Find the 2 consecutive prime numbers that the product is between the given ranges.
=> Square root of 1000 = 31.6
=> Square root of 1500 = 38. 7
Now, we have the square root value of both number ranges. The only consecutive prime numbers that we have is 31 and 37 that is in 31.6 and 38.7.
=> Let us now find the product of 2 consecutive prime numbers
=> 31 x 37
=> 1147
1147 is more than 1000 but less than 1500. Thus, the pin number of Maritza is 1147.

It’s going to be d. 4x^2-4x-19’
