#### Answer

Dear Cat,

1, 4, 10, 19, 31, 46 your answer

Let us break it down...

The first thing I do is to take the diference of the numbers next to each other

4-1=3

10-4=6

19-10=9

31-19=12

now notice the pattern or the diference of the answer 3,6,9,12 all are 3, so the next number would be 12+3=15 or add 15 to 31 to equal 46

46-31=15 now continue with what you know, x-31=15 and that would be 46

Who am I, see all my videos on Youtube...

46. you add three thE first time, six the next, nine and so on

46.

Add 3 to each progression.

46

46

1 + 3 = 4

4 + 6 = 10

10 + 9 = 19

19 + 12 = 31

31 + 15 = 46

I'm pretty sure it's 46 .. You add each number by three.

1+3=4 , 4+6=10 , 10+9=19 , 19+12=31 , 31+15=46

4 - 1 = 3

10 - 4 = 6

19 - 10 = 9

31 - 19 = 12

Just add 3 to the result everytime, and add it to the last number.
