Question

Write the AP whose second term is 13 and the difference of the fourth term from the eighth term is 16

Answer 1

Answer:

Step-by-step explanation:

a2=13

a8-a4=16

an=a+(n-1)d

a8=a+7d

a4=a+3d

a8-a4

=a+7d-(a+3d)=16

a+7d-a-3d=16

4d=16

d=4

a2=a+d

a+d=13

a+4=13

a=9

Using, a=9 and d=4,

AP=9,13,17,21.........
