Answer 1

Hii friend!!

Given, 5th term is 5 and common difference is -3
a5 = a + 4d = 5
a + 4(-3) = 5
a -12 = 5
a = 17

first term ;
a = a1 = 17

second term ;
a2 = a + d = 17 + (-3) = 17-3
a2 = 14

third term ;
a3 = a + 2d = 17 +2(-3) = 17-6
a3 = 11

The required AP :
17,14,11,.....

hope it helps

Answer 2

Given, 5th term is 5 and common difference is -3

a5 = a + 4d = 5

a + 4(-3) = 5

a -12 = 5

a = 17

first term ;

a = a1 = 17

second term ;

a2 = a + d = 17 + (-3) = 17-3

a2 = 14

third term ;

a3 = a + 2d = 17 +2(-3) = 17-6

a3 = 11

The required AP :

17,14,11,.....
