Find two consecutive numbers that sum to five: three and two, three and one, five and one, or three and five.
This question asks us to find two consecutive numbers that sum to five. Consecutive numbers follow each other in order. Are any of the pairs of numbers consecutive?
How about three and two? If we were counting backward, three, two, one, zero, and three and two follow each other in order. Does three and two sum to five?
Here we have three blue counters and two orange counters. Let’s count how many that makes all together: one, two, three, four, five.
Three and two sum five. The two consecutive numbers that sum to five are three and two.
