In an ap the 24thterm is twicethe 10th term.prove that the 36th term is twice the 16th term.

Answer»

According to the QUESTION,



24th term = 2( 10th term )


a + 23d = 2 ( a + 9d )


a + 23d = 2a + 18d


23d - 18d = 2a - a


5d = a ----1equation





Hence,

To Prove : 36th term = 2( 16 th term )


RHS = 2 ( a + 15 d )

= 2a + 30d

= 2( 5d ) + 30d

= 10d + 30d

= 40d



LHS = 36th term

= a + 35D

= 5d + 35d

= 40d




40d = 40d


RHS = LHS



PROVED.
