Question

Find the next probable number: 22, 19, 16, 13, 10.

Answer 1

Answer:

22,19,16,13,10,7,4,1

Answer 2

Answer:

7

Step-by-step explanation:

as the diff between each no is 3

let nos be like a1,a2,a3,a4,a5,a6

d1=a1-a2 == 22-19 = 3

d2= a2'a3 == 19-16 = 3

same with all

therefore a5-d is the answer

10-3 = 7
