Answer 2

Answer:

Arithmetic sequence is

-12 , 6 ,24, 42

Arithmetic sequence :

Arithmetic sequence are ordered sets of numbers that have a common difference  between each consecutive term.

"If we add or substract the same number each time  to make the sequence , it is an arithmetic sequence"  Or

"Every term is obtained by adding a fixed number (positive or negative or zero ) to its previous term "

The following  is an arithmetic  sequence as every term is obtained by adding a fixed number for its previous term .

Step-by-step explanation:

_,_,24,42​

Third number = 24

Fourth number = 42

Let the first number be x and the second number be y .

Thus, the arithmetic sequence is x , y ,24,42,...

⇒ 24- y = 42-24

⇒y = 24-42+24

⇒ y = 6

Also , y - x = 24-y

⇒6-x = 24-6

⇒x = 6 -24+6

⇒ x = -12

Therefore , the first and the second . Number are -12 and 6 respectively

Thus, the arithmetic sequence is

-12 , 6 , 24, 42
