Question

Find 7th term .. 216,36,6..

Answer 1

-864 is the 7th term

Answer 2

–864

Explanation:

i don't know if you mean A.P or G.P

but lets use A.P

T1(a) = 216

d(common difference) = T2 – T1 = 36 – 216 = –180

T7 = a + (n – 1)d

= 216 + ( 7 – 1)–180

= 216 + (6) – 180

= 216 – 1080

= –864

i hope this helps
