Question

Look at this series $7,10,8,11,9,12$. What number should come next ?

• A. $7$
• B. $10$
• C. $12$
• D. $13$

Answer 1

The correct option is B

$10$

Explanation of the correct option.

Step $1$: Identify the pattern.

Given: $7,10,8,11,9,12$

In the given series, we can see that the digits at even places and odd places are increasing by one.

For example:

$$\begin{gathered} 8=7+1,9=8+1 \\ \mathrm{And}, \\ 11=10+1,12=11+1 \end{gathered}$$

Step $2$: Compute the next term of the series.

Since the next term is at odd's place therefore,

Next term of the series$=9+1$

Next term of the series$=10$

Hence, Option $B$ is the correct answer.
