Question

Counting by fives, write numbers starting from $7913$.

Answer 1

Write numbers starting from $7913$ counting by fives.

In counting by fives each number is $5$ more than the previous number.

To obtain numbers by counting by fives, start from $7913$ and keep adding $5$ to get the next number as follow:

$$\begin{gathered} 7913+5=7918 \\ 7918+5=7923 \\ 7923+5=7928 \end{gathered}$$

Hence, counting by fives the next numbers starting from $7913$ are $7918,7923,7928.....$
