Question

Have a look at the series: $4,7,5,8,6,9,\dots\dots,\dots$

What number should come next?

• A. $7$
• B. $9$
• C. $10$
• D. $13$

Answer 1

If we observe series then each term of series follow the patterns like $+3,-2,+3,-2$ and so on.

• $4+3=7$
• $7-2=5$
• $5+3=8$
• $8-2=6$
• $6+3=9$

so the next term will be
$9-2=7$

option A is correct.
