• B. $4,3,2$
• C. $10,16,20$
• D. $6,7,8$

Answer 1

The correct option is A $10,15,20$

Say: Skip counting helps you to count groups of objects faster.
Let us skip count and find the missing numbers.

Steps:
$\bullet$ We have to skip count by 5s to fill in the missing numbers.
$\bullet$ The first number is 5.
$\bullet$ The second number will have 5 + 5 = 10 written on it.
$\bullet$ Similarly, we can skip count by 5 to get 15, 20, and 25
$\bullet$ We can see that the numbers are arranged in increasing order because we are adding the same number to each number to get the next number.
$\bullet$ The sequence is 5, 10, 15, 20, 25.
$\bullet$ Hence, option A is the correct answer.
