Question

Choose the equation that could be used to find two consecutive integers whose sum is 67.

n + n = 67
n + (n + 2) = 67
n − (n + 1) = 67
n + (n + 1) = 67

Answer 1

Any ideas?

Answer 2

Well, it's obviously not the third one because you want a sum. So you can rule that one out.
Now, consecutive integers are integers in order (+1), such as 1, 2, 3, 4, ...

Answer 3

Recall: consecutive integers are numbers obtained by counting by ones from any number in the set of integers

Answer 4

and i can rule out the first one because there is no consecutive integers in that equation right?

Answer 5

Let n = any integer.

Answer 6

The next consecutive integer obtained by counting by ones would be n + 1.

Answer 7

so it is the last one.

Answer 8

Correct.

Answer 9

find two consecutive integers whose sum is 67

$$\Huge n + (n+1) = 67$$
