The number which best completes the sequence below is:1 1 3 2 4 6 5 25 ?
4
25
13, 14, 16 - the numbers increase by 1 then 2 each time
The next number would be 18.3, 4, 6, 9, 13To get from 3 to 4, you need to add one. To get from 4 to 6, you need to add two. To get from 6 to 9, you need to add three. And so on and so on.
18
18
18
18 (3+1 4+2 6+3 9+4 13+5)
13 20 12
It is 24+7 = 31
Continuing the sequence would be the the numbers 24, 31, 39.
The difference between consecutive numbers is 1, 2, 3, 4. So the next difference will be... Added to 13 gives...
18 Add to previous number by 1 then 2 then 3 then 4 and 5 3+1=4 4+2=6 6+3=9 9+4=13 so then 13+5=18
Nothing "completes" the sequence because it goes on forever - without end.
