Consider the sequence - 101, - 91, - 81, - 71, ...

What is the next number?

-61

Step-by-step explanation:

The sequence appears to + 10 after every number to the left.

For example, - 101 the first number in the sequence, when + 10 is applied equals - 91, which is the second number, and the pattern repeats

Using this logic, the next number would be:

-71+10=-61

-61

Step-by-step explanation:

-101+11=-91

-91+11=-81

-81+11=-71

-71+11=-61
