Question

18,20,10,6,? Solve this qustion

Answer 1

The given sequence is:

18, 20, 10, 12, 4, 6 , ?

We have to find, the value of missing number (?).

Solution:

To add 2 to the first number, we get the second one

18 + 2 = 20

10 + 2 = 12

4 + 2 = 6

Since, we observe only the first number from the pair

18, 10, 4

18 - 8 = 10

10 - 6 = 4

4 - 4 = 0 (first number of next pair)

By adding 2 , we get

0 + 2 = 2 (second number of next pair)

∴ The values of missing numbers (?) = 0, 2

Thus, the missing numbers are "0 and 2".
