Answer 1

Answer:

9,12,15,18,21

Step-by-step explanation:

Lets consider AP as     a, a+d, a+2d, a+3d, a+4d

Now given that product of  first and last term is 189

a* (a+4d)=189---(1)

given that difference between and 4th term is 9

a+3d -a=9

d=3;

solve (1) we get a=9 and a=-21

lets consider positive value a=9

substitute a and d values in AP a, a+d, a+2d, a+3d, a+4d

Now AP becomes 9,12,15,18,21
