Series have two sequences.
1st sequence = 20,19,17,14(It is in the pattern as -1,-2,-3,-4.....)
2nd sequence = 20,16,13,11(It is in the pattern as -4,-3,-2,-1.....)
Therefore next number in 1st sequence=14-4 = 10
And the next number in the 2 sequence=11-1 = 10 - 12 years agoHelpfull: Yes(3) No(0)

- Split as 2series 20 19 17 14 x
20 16 13 11 x
1st series
20-1= 19
19-2=17
17-3=14
So next 14-4=10
Similarly 2nd series
20-4=16
16-3=13
13-2=11
So next 11-1=10
