Continue the pattern 31, 5, 32, 10, 33, 15, blank blank blank

34, 20, 35, ...

Step-by-step explanation:

From what I see, it is alternating between two patterns: +5 starting at 5, and +1 starting at 31.

34 , 20, 35

Step-by-step explanation:

31, 5, 32, 10, 33, 15,

This is really two sequences

Look at terms 1,3,5

31, 32,33

We are adding 1 each time

Then look at terms 2,4,6

5,10,15

We  add 5 each time

It goes add 1 to the odd term, then add 5 to the even term, then add 1 to the odd term,

Add 1 to the odd term

33 +1 = 34

Add 5 to the even term

Then 15 +5 = 20

Then add 1 to the odd term

34 +1 = 35

72 is the answer to this problem
