Question

lisa starts counting at 830. she counts by fives. what two numbers does lisa count next? choose 1 answer: a 840 and 845 b 840 and 850 c 935 and 940 d 835 and 840

Explanation:

Step1: Understand the counting rule

Lisa counts by fives, so each next number is previous number + 5.

Step2: Find the first next number

Start at 830, first next number: \( 830 + 5 = 835 \)

Step3: Find the second next number

Second next number: \( 835 + 5 = 840 \)

Wait, there's a mistake in the previous thought. Wait, no, let's re - check. Wait, the options: Let's recalculate. Wait, 830 + 5 = 835, 835+5 = 840. So the two numbers after 830 when counting by fives are 835 and 840. Let's check the options. Option D is 835 and 840.

Wait, maybe I made a mistake earlier. Let's do it again.

Step1: Determine the increment

The increment is 5 since she counts by fives.

Step2: Calculate the first next number

Starting from 830, the first number after 830 is \( 830+5 = 835 \)

Step3: Calculate the second next number

The number after 835 is \( 835 + 5=840 \)

Answer:

D. 835 and 840
