Question

The sixth term of the ap is zero prove that the 31st term is 5 times the 11th term

Answer 1

Answer:

0

Step-by-step explanation:

6 th term = 0

a +5d = 0

a = -5d

thus,

31st term = 5( 11th terh )

a +30d = 5( a +10d)

-5d + 30d = 5 ( -5d +10d)

25d = 5 ( 5d)

25 d = 25 d

0 = 0

hence proved l.h.s. = r.h.s
