Question

The 10th term of the G.P. 24,12,6,....... is​

Answer 1

Answer:

a10= -84

Step-by-step explanation:

a1=24

a2=12

d=a2-a1

d=12-24

d= -12

a10=a+9d

a10= 24+9*-12

a10=24-108

a10= -84

Answer 2

Step-by-step explanation:

Here a= 24, d = 12 - 24 = - 12, n = 10

$\because \: t_n = a + (n - 1)d \\ \\ \therefore \: t_{10} = 24+ (10 - 1) \times ( - 12)\\ \\ \therefore \: t_{10} = 24+ 9 \times ( - 12)\\ \\ \therefore \: t_{10} = 24 - 108\\ \\ \huge \red{ \boxed{\therefore \: t_{10} =- 84}}$
