5th term = 0
a + 4d = 0
a = -4d
To prove : 23rd term = 3 ( 11th term )
a + 22d = 3 ( a + 10d )
-4d + 22d = 3 ( -4d + 10d )
18d = 18d .......PROVED......
a + 4d = 0
a = -4d
To prove : 23rd term = 3 ( 11th term )
a + 22d = 3 ( a + 10d )
-4d + 22d = 3 ( -4d + 10d )

Hey !!
5th term = 0
a + 4d = 0
a = -4d
23rd term = 3(11th term )
a + 22d = 3 ( a + 10d )
-4d + 22d = 3 ( -4d + 10d )
18d = 18d
