The list below shows the years the Cricket World Cup was held since 1992. 1992, 1996, 1999, 2003, 2007, 2011, and 2015. Adam says the Cricket World Cup has been held every four years since 1992. Adam is not correct. Explain how you know.

The difference between 1992 and 1996 is four. 92 add four is 96. And the difference between 1996 and 1999 is only three. 96 add three is 99. Adam said the World Cup has been held every four years. And we just need to explain how we know he’s incorrect.

We know that Adam is not correct because the difference between 1996 and 1999 is three years. So the World Cup was not held every four years. We checked Adam’s statement by finding the difference between 1992 and 1996, which was four years. And then, we checked the difference between 1996 and 1999, which was only three years. So this helped us to explain how we knew that Adam was not correct.
