Which statement is a contrapositive of p? p: if x is divisible by 4, then x is divisible by 2. a. if x is divisible by 2, then x is divisible by 4. b. if x isn’t divisible by 4, then x isn’t divisible by 2. c. if x isn’t divisible by 2, then x isn’t divisible by 4. d. if x is divisible by 2, then x isn’t divisible by 4. e. if x isn’t divisible by 4, then x is divisible by 2.

B. If x isn’t divisible by 4, then x isn’t divisible by 2.

Step-by-step explanation:

contra positive statement is obtained by interchanging the hypotheses and conclusion of the inverse statement.

Here given that statement p is

If x is divisible by 4, then x is divisible by 2.

To write contrapositive of p, first we interchange the hypothesis.

Then it would look like

If x is divisible by 2, then x is divisible by 4.

Now we make conclusion as negative. i.e.

If x is not divisible by 4, then x is not divisible by 2.

This is the contra positive statement of p

Hence option B is right.

C. If x isn’t divisible by 2, then x isn’t divisible by 4.

I just took a test with this question and this was the right answer

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
