Question

the fourth term of an arithmetic progression is 6 more than its second term. if the eight term is 26,tgen find the arithmetic progression​

Answer 1

Answer:

AP is 5,8,11,14

Step-by-step explanation:

so fourth term= a+3d

and second term= a+ d

ATQ(according to question), a+3d= 6+a+d

= 3d-d= 6( as a on both sides will get cut)

= 2d=6

so d= 3

now the eighth term is 26

a+7d=26

a+7*3= 26

a+21=26

a=26-21

a= 5

so AP is 5, 8, 11, 14..... and so on.
