Find the oth term of the geometric sequence 7, 14, 28, ...

yaroslaw [1]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

$a_n=7\cdot \:2^{n-1}$

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

$a_n=a_1\cdot r^{n-1}$

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

$\frac{14}{7}=2,\:\quad \frac{28}{14}=2$

The ratio of all the adjacent terms is the same and equal to

$r=2$

now substituting r = 2 and a₁ = 7 in the nth term

$a_n=a_1\cdot r^{n-1}$

$a_n=7\cdot \:2^{n-1}$

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

$a_n=7\cdot \:2^{n-1}$

What is triangle ABC ?<br><br> (line segments)

Bess [88]

Triangle ABD and ADC are righttriangles so u can use the Pythagorean theorem/triples. the triples are 3/4/5 and 5/12/13. 12 is 4x3, and 15 is 5x3, so BD is 3x3, which is 9. AC is 13, as it is part of the Pythagorean’s triples

Two types of tickets are available for a charity ball event: $18 for a reserved seat and $9 for general admission. The number of

Murljashka [212]

Answer:

# of reserved seats = R; # of general admission seats = G

G - R = 85

$18R + $9G =$3600

Multiply 1st equation by 18: 18G - 18R = 1530

Rearrange 2nd equation: $9G + $18R =$3600

Combine the equations: 27 G = 5130

G = 190

R = 105

Write a slope-intercept equation for a line that passes through (-4, 6.7) and (0, 6.7).

Shkiper50 [21]

Answer:

Step-by-step explanation:

In both the point, y-coordinates are same. So, the line is parallel to x-axis

Slope of the line parallel to x-axis =0

m = 0

Equation : y =6.7
