Which of these true conditional statements has a false converse ?

Option B has a false converse.

Step-by-step explanation:

When we switch the hypothesis and conclusion of a conditional statement, then it is called the converse of that statement.

Here options A and C have a true converse.

If n is even then it is divisible by 2.

If 2x=4, then x=2.  

But if x>10, then x>5 does not have a true converse.

We can write the converse as : if x>5 , then x>10 . This cannot be necessarily true as you can have x=6 which is not >10.

Therefore, option B has a false converse.

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
