Look at the steps and find the pattern.step 1step 2step 3How many dots are in the 4th step?dotsSubmit

Answer 1

40

Explanation

Step 1

a)initially we have 8 dots

after that

in step 2, we have a new row and , now there are 8 dots per row, so

$\begin{gathered} \text{new row} \\ and\text{ number of dots= previous +1} \end{gathered}$

in step 3, we should have

$\begin{gathered} new\text{ row, it means now, there are 3 rows} \\ \end{gathered}$

and

$\begin{gathered} and\text{ number of circles = previous +1} \\ \text{ number of circles =}8+1=9 \\ \text{ number of circles =}9 \end{gathered}$

as we can see, the rule works

Step 2

now, to find the patter in step 4, just apply

$a\text{ new rounds, now, there are 4 row}$

and

$\begin{gathered} and\text{ number of dots = previous +1} \\ \text{ number of dots = 9}+1=10 \\ \text{ number of dots=}10 \end{gathered}$

finally, to know the number of dots

Multiply the number of row, by the number of dots per row, so

$\begin{gathered} \text{Number of dots=4}\cdot10 \\ \text{Number of dots=}40 \end{gathered}$

therefore, the answer is 40
