What happens When a random sampling frame has a systematic pattern in the listing of sampling units rather than a random pattern?

You get a non-random sample and any analysis based on the assumption of randomly distributed variables is no longer valid.
In particular, your estimates of any variables are likely to be biased and your error estimates (standard errors or sample variances) will be incorrect. Any inferences based on statistical tests will be less reliable and may be wrong.

Is systematic sampling biased?
Often not, but it is important to check that there is no systematic pattern in the skip.To take an unlikely example, suppose you wanted to sample the values of 10% of houses on a street with 200 houses on it. A possible systematic sampling scheme would be to select a random house number to start with and then select every 20th house number (looping back when the number exceeds 200). If the first house number is odd then all houses in the sample are odd numbered and, therefore, on the same side of the street. If the street runs East-West, the sample could consist exclusively of South-facing gardens - attracting a price premium!
Are you able to list all composite numbers up to 3000?
Yes, but it is not practical on this site. There are over 2,600 such numbers and there is no systematic pattern to them so it is not practical to do it here. However, you can follow the related link for primes in the range and remove them from 2- 3000 to obtain your answer.

What is a sample of a population that has been selected using a pattern?
A sample of a population that has been selected using a pattern is when a researcher selects every 10th person from a list or sampling frame. For example, if a researcher wants to study the attitudes of employees in a large company, they may select every 10th employee from the company directory. This method ensures a systematic pattern in selecting the sample.
