Numbers - Elementary Math

John’s dad was walking in the car rental lot to pick up their rental car. He passed several spots on the left. They were numbered as follows:

201 203 205 207

Which number would he most likely see on the next parking lot on the left?

a. 200
b. 206
c. 209
d. 212

Answer : c

Why:
The student should notice the following:
a. The parking lot numbers are all odd numbers so the next number coming should be an
odd number.
and
b. Each parking lot number is increased by 2 from the previous number.

Therefore if we add 2 to the last number which is 207 we should get 209 as follows:
207 + 2 = 209
