Question

Find A.P. , if a= 18 and d = -5.​

Answer 1

Given,

a (first term) = 18

d (common difference) = -5

first term = 18

second term = 18+(-5) = 18-5 = 13

third term = 13+(-5) = 13-5 = 8

fourth term = 8+(-5) = 8-5 = 3

fifth term = 3+(-5) = 3-5 = -2

and so on...........

Hence the A.P formed if a = 18 and d = -5 is 18,13,8,3,-2,.......

Answer 2

a=18

d=-5

then AP=a+d,a+2d,a+3d,a+4d...

=18+(-5),18+2(-5),18+3(-5),18+4(-5)...

=13,8,3,-2...

and so on
