  1. For this pattern, we start with 4, and then the next number in the sequence is 20. How do 4 and 20 relate to each other?
    Well, 4 5 = 20, so let's see if that's what the pattern is...

    20     5 = 100

    What's the next number in the sequence? 100, so it looks like that is what the sequence is.

    100 5 = 500

    Yep :D
    The pattern for 13 is multiply by 5.

    14. For this one, we start with 44, then go to 22. We know that 44 divided by 2 is 22. But 22 divided by 2 is 11, not 20, so what would the next step be? Well, 22 minus 2 is 20, so let's see what we have to work with after this. 20 divided by 2 is 10, which is the next number in the sequence, and 10 minus 2 is 8.

    The pattern for problem 14 is divide by 2, then subtract 2, and repeat.

    19. The expression is 7 + 3     6 = ?

    According to the Order of Operations (PEMDAS), we need to do any multiplication in the problem before addition.

    3 6 = 18

    7 + 18 = 25

    7 + 3     6 = 25

    20. The expression is (6 - 4) 9

    Again, referring to PEMDAS, we can see that items in parentheses come first.

    6 - 4 = 2

    So now the problem is 2     9 = ?

    2 9 = 18

    So,

    (6 - 4)     9 = 18

    Hope that helped =)
