Question

What is the 20th number in this sequence?

896, 3687, 749, 34448, 836, ...

Answer 1

Those seem to me to be the number equivalents of words for numbers. That sounds confusing, but here is what I mean. 896 is two. Look at your phone pad. 8 is T, 9 is W, 6 is O. Get it? 3687 is four, 749 is six, 34448 is eight, 836 is 10, etc..  

So now that you know the number sequence (2,4,6,8,10,...), then find the 20th number in the sequence, convert it to its word equivalent, and then spell it on your phone pad.

Answer 2

Oh my brain hurts!!! I don't see any pattern.

Answer 3

The 20th number in this sequence is 36789
