Question

How many dots will be there in the fifth step?

• A. 8
• B. 12
• C. 14
• D. 10

Answer 1

The correct option is D 10


On representing the number of dots on a number line, we observe:


So, in each step, the number of dots is increasing by 2.

Thus, in the fourth step, there will be
(6 + 2) dots = 8 dots
In the fifth step, there will be
(8 + 2) dots = 10 dots

From the number line, we can also see that:

Therefore, in the fifth step there will be ten blocks.

Representing this in a tabular format, we get
