Pattern recognition is critical to reading braille. below is the beginning of a sequence of numbers. find the sum of the first four numbers in the sequence. 3, 6/3, 12/9

The sum is 7 2/9.

The first 3 numbers of the sequence can be written as
3/1, 6/3, 12/9

Each numerator is being doubled and each denominator is being tripled; this means the fourth term would be 24/27.

Now we can simplify these in order to add them:
3/1 = 3
6/3 = 2
12/9 = 1 1/3
24/27 = 8/9

Adding the whole numbers, we have 6; now we must add 1/3 + 8/9.  The LCD for these two is 9:
3/9 + 8/9 = 11/9

We have 6 11/9; simplifying this we have 7 2/9.

3x - 8 = -2

3x -8+8 = -2 +8

3x = 6

3x/3 = 6/3

x = 2

s

x - 6

( 2-6)

= -4

that is the value of x -6

= -4
