Position to term rule of 2, 6, 10, 14, 18<br><br> multiply by _____ and subtract by _____
andreyandreev [35.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

2, 6, 10, 14, 18

An arithmetic sequence has a constant difference and is defined as

\:a_n=a_1+\left(n-1\right)d

compute the differences of all the adjacent terms

6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4

The difference between all the adjacent terms is the same.

Thus,

d=4

and

a_1=2

Therefore, the nth term is computed by:

a_n=4\left(n-1\right)+2

a_n=4n-2

Thus, position to term rule of 2, 6, 10, 14, 18  multiply by __4___ and subtract by __2__.

Help pls thx guys photo attached
alexdok [17]

Answer:

x = 18

A = 110

Step-by-step explanation:

Angles A and B are supplementary angles so they add to 180 degrees

A + B = 180

5x+20 + 9x -92 = 180

Combine like terms

14x -72 = 180

Add 72 to each side

14x-72+72 = 180+72

14x = 252

Divide each side by 14

14x/14 = 252/14

x =18

A = 5x+20

  = 5*18 +20

   =90 +20

   = 110
