The sum of two numbers is 20 and their difference is 12.

4 and 16

Step-by-step explanation:

First, let's find first term using sum formula:

We know that d or common difference is 12 and only sum of two terms so n = 2.

Since sum of two numbers equal 20.

From above, subtract both sides by 12, solving for a1.

Therefore our first number is 4.

Finding next number, create an equation:-

Another number is 16

So 4 and 16 has 12 as difference because 4+12=16 and 16-12 = 4

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
