Question

4,8,12,7,11,18,9,.......,22

Answer 1

$\textbf{\large{Answer -}}$

4, 8, 12, 7, 11, 18, 9, $\textbf{\underline{13}}$, 22

Explanation :

When we move from starting of the series, we find that the sum of every two number is the third number.

i.e.,

$4 + 8 = 12$

$7 + 11 = 18$

$9 + 13 = 22$

Answer 2

Answer:

The missing number is 13.

Step-by-step explanation:

Given sequence,

4,8,12,7,11,18,9,.......,22

By observing the sequence,

We notice that,

4 + 8 = 12

7 + 11 = 18,

Thus, if x be the missing term of the sequence,

Then, 9 + x = 22

x =  22 - 9 = 13

Hence, the sequence would be,

4,8,12,7,11,18,9,13,22

That is, the missing number is 13.
