Step-by-step explanation:

Answer 2

first series : 63 , 65 , 67.....

second series : 3 , 20 , 37.........

nth term can be given by ; a + (n-1)d

nth term of first series = 63 + (n-1)2 ;

nth term of second series = 3 + (n-1)17;

equating the nth terms we get;

=> 63 + (n-1)2 = 3 + (n-1)17

=>. 60 = 15(n-1)

=> 4 = (n-1)

=> n = 5

therefore the 5th terms of both the series of AP are equal
