Question

write next 4 term of the ap, whose first term is 12 and common difference is 2 briefly​

Answer 1

The common difference of the Arithmetic Progression is - 3.

Step-by-step explanation:

Given:

First term of the Arithmetic progression(a) = 12

Fifth term of the Arithmetic Progression(a5) = 0

5 th term of the of the AP can be written as:

=> a + (5 - 1 )d = 0

=> a + 4d = 0

We know that a = 12 so we can substitute the value of a in this formula:

=> 12 + 4d = 0

=> 4d = - 12

d = -12/4

d = - 3

Therefore, the common difference(d) of the Arithmetic Progression is - 3.

Answer 2

Answer:

12 , 14, 16, 18, 20

Step-by-step explanation:

first term , a = 12

common difference , d = 2

a2 =  a + (2-1)d = 12 + 2 = 14

a3 = a +(3 -1)d = 12 + 4 = 16

a4 = a + (4-1)d = 12 + 6 = 18

a5 = a + (5-1)d  = 12 + 6 = 20

hence the term of AP

12 , 14, 16, 18, 20
