Question

Counting by fives, write numbers starting from $3505$.

Answer 1

Write numbers starting from $3505$ counting by fives.

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

To obtain numbers counting by fives, start from $3505$ and keep adding $5$ to get the next number as follows:

$$\begin{gathered} 3505+5=3510 \\ 3510+5=3515 \\ 3515+5=3520 \end{gathered}$$

Hence, counting by fives the next numbers starting from $3505$ are $3510,3515,3520.....$
