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

The series is $7,10,8,11,9,\mathrm{12...}$

The series is developed by adding $3$ and subtracting $2$ alternatively

$12$ ia the result of adding $3$ to previous one.

so the next term is $12-2=10$
