In a geometric sequence, A1 = 0.3 and r=3.Find A12, to the nearest integer

soldi70 [24.7K]

Step-by-step explanation:

We have,

First terms of geometric sequence, a = 0.3

Common ratio, r = 3

It is required to find the 12th term of a GP. The formula of the nth term is given by :

$T_n=ar^{n-1}$

Here, n =12

So,

$T_{12}=0.3\times 3^{12-1}\\\\T_{12}=0.3\times 3^{11}\\\\T_{12}=53144.1$

$T_{12}=53144$

So, the 12th term of the GP is 53144.

mihalych1998 [28]

Answer: p=−5

Step-by-step explanation:

Step 1: Add 2p to both sides.

p+2p=−2p−15+2p

3p=−15

Step 2: Divide both sides by 3.

3p/3 = −15/3

p=−5
