each number is 15 less than the previous number and -37-15=-52 so the next number should be -52. None of the options provided are correct.

Well, from what you present, each number in the sequence is 15 smaller than the previous one... logic would say -52. Where did this question (and answers) come from?

Smeta - please do not tag a new question onto an old one. Instead you should start a new question.

Here's a hint to solving this: if you consider the differences between each pair of numbers, you should see a pattern.
