Question

look at this series 40,33,27,22,18, what number should come next​

Answer 1

Answer:

15 should be the next number

Step-by-step explanation:

40-33= difference is 7

33-27= difference is 6

27-22= difference is 5

22-18= difference is 4

18-__= difference should be 4

so it is 15

Answer 2

Step-by-step explanation:

here we can observe that

40 - 33 = 7

33 - 27 = 6

27 - 22 = 5

22 - 18 = 4

let the next number be x where

when we minus x with 18 we should get 3

i.e

18 - x = 3

- x = 3 - 18

- x = - 15

therefore x = 15

therefore the next number will be 15
