Question

The sum of three consecutive numbers is 90. Write and solve an equation to find the SMALLEST integer.

Answer 1

Answer:29

Step-by-step explanation: the answer is 29 because if there are three consecutive numbers, we know that the second and third number must be one and two units larger respectively. As such you can subtract the difference from the combined number (1 (2nd number) + 2 (third number) = 3 --> 90 - 3 = 87). So, if you divide the new number (87) by three (the number of consecutive integers required for this question) the answer is 29. If the answer is 29, we know that the second and third number in the sequence must be 30 and 31. 29 + 30 + 31 = 90.
