How can I complete these 4 patterns:

For each pattern, a number is added or subtracted from the last number to get the next number.

For example:

17 + 15 = **32** + 15 = **47** + 15 = 62 + 15 = **77** + 15 = 92

The second one should be obvious.

For the third one, think about the difference between 33 and 17.

We'll be happy to check your answers.
