​

Answer 1

Answer:

The 3 numbers of the AP are 21,23,25

Step-by-step explanation:

let (a-d),a and (a+d) be the 3 numbers of the AP

given, (a-d)+a+(a+d) = 69

     =>                   3a = 69

     =>                     a  = 69/3

     =>                     a  = 23

also, given,

(a-d)a = 483

=> (23-d)23 = 483

=> 23-d = 483/23

=> 23-d = 21

=> d = 23-21

=> d = 2

therefore, the 3 numbers are (23-2) , 23 , (23+2)

=> 21,23,25
