Question

Fill in the missing values in the pattern:

-7, , 3, , 13,...

Answer 1

-2 and 8.

Explanation:

The difference between 3 and -7 = 3 - -7 = 10

and between 13 and 3 = 10 also.

So the missing 2 numbers are -5 + 5 = -2

and 3 + 5 = 8 so the pattern is

-7, -2, 3, 8, 13 where the common difference is 5.

Answer 2

-7, -2, 3, 8, 13....
