Find the common ratio of the geometric sequence 6, 48, 384, ...

gregori [183]

Answer:

r = 8

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = $\frac{a_{2} }{a_{1} }$ = $\frac{a_{3} }{a_{2} }$ = ..... = $\frac{a_{n} }{a_{n-1} }$

Then

r = $\frac{48}{6}$ = $\frac{384}{48}$ = 8

Area of triangle = (1/2)*base*height

20.335 = (1/2)*base*8.3

2*20.335 = base*8.3

(2*20.335) / 8.3 = base Use your calculator.

4.9 = base

base = 4.9cm
