The tutorial then formulates an equation and solves it to find the numbers, concluding with a verification of the solution.

What is the first step in solving a word problem involving consecutive numbers?

• Identify what the problem is asking

• Write down random numbers

• Guess the numbers

• Start solving the equation immediately

How can you represent three consecutive numbers using a variable?

• N, N+2, N+4

• N, N+1, N+2

• N, N-1, N-2

• N, N+3, N+6

If the first number is represented by N, what would the third consecutive number be?

• N+4

• N+2

• N+1

• N+3

What is the equation formed when the sum of three consecutive numbers is 138?

• N + N + 1 + N + 3 = 138

• N + N + 2 + N + 4 = 138

• N + N + 3 + N + 6 = 138

• N + N + 1 + N + 2 = 138

What are the three consecutive numbers whose sum is 138?

• 44, 45, 46

• 45, 46, 47

• 46, 47, 48

• 47, 48, 49
