**37 minutes**. Ask a Question.

I was asked to pick a number out of 380, 220, 99 or 256, to be the next number in the sequence 4,5,5,7,14,17,51,55,_

The pattern I can see is as follows:

55-51 = 4

17-14=3

7-5=2

5-4=1

But I can't figure out how to find the right number... can you help me? Thanks.

familahow?

the sequence are 4,5,5,7,14,17,51,55,...

5-4 = 1; 5(no in odd position)*1 = 5 (the number next to it)

7-5= 2; 7(no in odd position)*2 =14 (the number next to it)

17-14= 3; 17(no in odd position)*3 = 51 (the number next to it)

55-51=4;55(no in odd position)*4 = 220 (the answer)

get it?
