Answer:

3072

Step-by-step explanation:

ar^(n-1)=192

ar^7=192

Given: r=2

a×2^7=192

a×128=192

a=192/128

So the 12th term=

ar^(12-1)=x

ar^11=x

(192/128) × 2^11=x

3072=x

Answer:

3072

Step-by-step explanation:

Common ratio, r = 2.

Let a be the first term of the G.P.

Given, 8th term is 192.

∴ a₈ = 192

=> ar⁸⁻¹ = 192

=> ar⁷ = 192

=> a(2)⁷ = 192

=> a = 192/128

=> a = 3/2

Now,

12th term of G.P a₁₂ :

= ar¹²⁻¹

= (3/2) * (2)¹¹

= 3 * 2¹⁰

= 3072

Hope it helps!
