-42

Step-by-step explanation:

This is a recursively defined sequence; one where we're given the first term in the sequence and rule for generating consecutive terms. Here, our rule is "double the difference of the last term and three". We're told our first term, a1, is 0, so following our rule, we have

So the fourth term in the sequence will be -42.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
