OMG SOMEONE ANSWER MY QUESTIONNN I ASKED IT 5 TIMES ALREADY AND NO ONE HAS ANSWERED

I believe it’s C, because in a recursive rule you must have (n-1), this shows that you’re using the previous term to solve for the next one.

Using the factorised trinomial <img src="https://tex.z-dn.net/?f=%28n-2%29%284n-7%29" id="TexFormula1" title="(n-2)(4n-7)" alt="
andrew-mc [135]
4n² - 15n + 14<span> is always the product of two numbers, for it to be prime number, one of these factors must be either 1 or -1.

Case n - 2 = 1
That would be n = 3
Then </span>4n² - 15n + 14<span> = 5 , which is prime.

Case n - 2 = -1
That would be n = 1
Then </span>4n<span>² - 15n + 14 = 3, which is also prime.

Case 4n - 7 = 1
That would be n = 2 and that makes other factor (n-2) zero so it's not prime

Case 4n-7 = -1
That would be n = 3/2 which is not integer, so </span>4n<span>² - 15n + 14 will not be interger.

For any other n values, </span>4n<span>² - 15n + 14 will be composite number since it is product of two factors.

Therefore we are left with n = 1 and n = 3; only two values of n.</span>

What is the converse of the linear pairs theorem
marysya [2.9K]
The converse of a logicalstatement is a s tatement formed by reversing the parts of the statement.

For example, the logical statement "A implies B" has a converse of "B implies A"

The linear pairs theorem states that "<span>if two angles form a linear pair, then they are supplementary".</span>

The converse of the linear pairs theorem is therefore, "if two angles are suplementary, then they form a linear pair".
