21 and 13.. 21-13=8 21+13=34 34/2 = 17,+4 = 21... 34-21 = 13
55
The common difference is 13 because 21-8=13, 34-21=13, and 34-47=13.
-13 + 34 = 21
Cow = x Chicken =y x+y=34 -> x=34-y 4x+2y=100 4(34-y)+2y=100 126-4y+2y=100 -2y=-26 y=13 (13 chickens) x=34-13=21 (21 cows) There are 21 cows and 13 chickens.

If you mean: 1 1 2 3 5 8 13 21 then the next number is 13+21 = 34
1, 2, 13, 26 1, 2, 17, 34
1, 2, 13, 26 1, 2, 17, 34
the answeer is 26
