Question

Identify the option in which the numbers show skip counting by 5.

• A. $2,3,4,5$
• B. $70,75,85,100$
• C. $12,22,32,42$
• D. $36,41,46,51$

Answer 1

The correct option is D $36,41,46,51$

Say: Let us identify the option that counts by 5 or skips 5 counts.

Steps:
$\bullet$ Skip 5 counts means to add 5 to each number to get the next number.

$\bullet$ The first number in option A is 36. So, 36 + 5 = 41, 41 + 5 = 46, 46 + 5 = 51. This is obtained by skip counting by 5s, so this option is correct.

$\bullet$ The first number in option B is 2. So, 2 + 5 = 7, but here the next number is 3. This is obtained by skip counting by 1s, so this option is incorrect.

$\bullet$ The first number in option C is 10. So, 10 + 5 = 15, but the next number here is 20. This is obtained by skip counting by 10s, so this option is also incorrect.

$\bullet$ The first number in option D is 70. So, 70 + 5 = 75, 75 + 5 = 80, but here the next number is 85. So, count by 10, 85 + 10 = 95, but the next number is 100, i.e., count by 15. There is no consistent skip counting. Therefore, this option is incorrect.

$\bullet$ Hence, option A is the correct answer.
