X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence. Find the constant difference between terms. Give a formul
Anna007 [38]

Common difference between the terms is 36

Formula for nth term is a_n=36n-11

27th term is 961

Given :

X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence

To Find:

We need to find the constant difference between the given terms and also find the nth term . Also find the 27th term .

To find the difference , we need to take the difference of consecutive terms

2x+11-x=x+11\\\\4x-3=(2x+11)= 4x-3-2x-11=2x-14

Both the common differences are equal

x+11=2x-14\\Solve \; for \; x\\Subtract \; x\\11=x-14\\Add \; 14\\x=25

First term is 25

second term is 2(25)+11=61

Difference is 61-25=26

Common difference = 36

Use nth term formula is

a_n=a+(n-1)d\\a=25 (first term )\\d=36\\a_n=25+(n-1)(36)\\a_n=25+36n-36\\a_n=36n-11

To find 27th term , replace n with 27

a_{27}=36(27)-11=961

The length of a garden is four more than twice its width, w. Which expressions represent the area of the garden? Select all that
fgiga [73]

Answer: the options that apply are

1) w(2w + 4)

5) 2w² + 4w

Step-by-step explanation:

The formula for determining the area of a rectangular garden ins expressed as

Area = length × width

The length of a garden is four more than twice its width, w. The expression for the length would be

Length = 2w + 4

Therefore, the expression that represents the area of the garden would be

w(2w + 4)

Expanding the brackets, it becomes

2w² + 4w
