Answer:

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.

Step-by-step explanation:

The statement describes an arithmetic progression, which is defined by following formula:

p(n) = p_{1}+r\cdot (n-1) (1)

Where:

p_{1} - First element of the sequence.

r - Progression rate.

n - Index of the n-th element of the sequence.

p(n) - n-th element of the series.

If we know that p_{1} = 1, n = 2 and p(n) = 5, then the progression rate is:

r = \frac{p(n)-p_{1}}{n-1}

r = 4

The set of elements of the series are described by p(n) = 1 + 4\cdot (n-1).

Lastly, if we know that n = 300, then the 300th term of the sequence is:

p(n) = 1 + 4\cdot (n-1)

p(n) = 1197

And the next three terms of the sequence are:

n = 5

p(n) = 1 + 4\cdot (n-1)

p(n) = 17

n = 6

p(n) = 1 + 4\cdot (n-1)

p(n) = 21

n = 7

p(n) = 1 + 4\cdot (n-1)

p(n) = 25

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.

Can I get help with this question?
worty [1.4K]
The answer is 157 degrees because the line segment is 180 and if <AFB is 23, you take 23 away from 180 and you should get 157. To check, add 157 to 23 or take away 157 from 180.

#5) 7.065 sq. ft.
#6) 36 ft
#7) 200.96 sq. ft.
#8) 176.625 sq. ft.

Explanation
#5) Converting 18 inches to feet, 18/12 = 1.5.  The area of the circle would be given by A=3.14(1.5)² = 3.14(2.25) = 7.065 sq. ft.

#6) The radius is 18 inches, so the diameter is twice that:  18*2 = 36 inches.  Converting this to feet, we have 36/12 = 3 feet.  Each stone is 3 feet across.  Laying 12 of them against each other would give us a total length of 12*3 = 36 feet.

#7) The radius of the entire mirror with frame is 20/2 = 10.  The area of the entire mirror with frame is A=3.14(10²) = 3.14(100) = 314 in².
The area of the mirror without the frame is A=3.14(6²) = 3.14(36) = 113.04 in².

The difference between the two will give the area of the frame:
314-113.04 = 200.96 in²

#8) The area of the circular region is given by A=3.14(7.5²) = 176.625 ft²
