Jeanette is not correct. In an arithmetic sequence, to find the next number, you have to add the common difference. If the first number is - 27, to find the next number you have to add 5, making the next number - 22. The pattern of adding 5 would continue making the first 5 terms of the sequence : - 27,-22,-17,-12, - 7.
