Correct! Wrong!

The right response is complex. Decrease and increase, the first pair of words, are opposites. To make something smaller, use the term decline, and to make something larger, use the word increase.

There is a pattern to the numbers in the box. What number should the question mark be replaced with?

Correct! Wrong!

The right response is 19. (28, -4) is the pattern that goes across the first row. 21 is 13 plus 8, while 17 is 21 – 4. The pattern is the same in the second row: 24 – 4 equals 20, and 16 + 8 equals 24. The bottom row needs to adhere to the same guidelines as well. The pattern will function if we enter 19: 19 + 8 equals 27, and 27 – 4 equals 3. 19 is therefore the right response.

5 12 9 16 13 ?

Correct! Wrong!

Twenty is the correct response. The series starts with the number 5. Twelve comes next, which indicates that seven was added. Nine comes next, indicating that three was deducted. 16 is the next number, indicating that 7 was added once more. This indicates that +7, – 3 is the pattern in this series. By adding 7 to 13, we can arrive at the right answer of 20, by following this strategy.

What would make the displayed picture complete?

Correct! Wrong!

Alex and Mitch made twenty cookies. Alex ate four of them, while Mitch consumed half. How much of the cookies remained?

Correct! Wrong!

The correct answer is 6 cookies. There were 20 cookies to start, and if Mitch ate half of them, that means we must divide 20 by 2 to find out how many he ate:

20 ÷ 2 = 10 cookies
If we then subtract the 10 cookies Mitch ate, we get 10 cookies remaining:

20 – 10 = 10 cookies

Alex then ate 4 cookies, which means we must subtract 4 from the 10 remaining cookies to find out how many were left:

10 – 4 = 6 cookies
