After the first term in a sequence, the ratio of each term to the preceding term is r. If the first term is a, what is the third

irinina [24]

Answer:

The 3rd term is

$ar^2$

Step-by-step explanation:

From the given information, the first term of the sequence is

$a_1=a$

The common ratio of the sequence is

$r$

The explicit formula for a geometric sequence is :

$a_n=a_1(r^{n-1})$

To find the third term, we put n=3 to get:

$a_n=a(r^{3-1})$

This simplifies to:

$a_3=ar^2$

Solve the equation x. 3 = x/3 + 4

Gennadij [26K]

Answer:

x = 5

Step-by-step explanation:

3 = x/ 3 + 4

This is same as

3/1 = x/ 3 + 4

Then cross multiply

1(x + 4) = 3× 3

x + 4 = 9

x = 9 - 4

x = 5
