Answer:

hello

Step-by-step explanation:

adjacent angles are equal to 180 degrees,

(2x + 9) + (5x + 3) = 180 \\   8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x  =  \frac{168}{8}  \\ x = 21  \\  \\

but, for some reason, does not match the answers…

Can the answers be wrong?

or I miscalculated…

i hope it helps have a nice day

Answer:

The formula is 10 - 3n

Step-by-step explanation:

For an nth term in an arithmetic sequence

U( n ) = a + ( n - 1)d

Where n is the number of terms

a is the first term

d is the common difference

From the sequence above

a = 7

d = 4 - 7 = - 3

The formula for an nth term is

U(n) = 7 + (n - 1)-3

= 7 - 3n + 3

The final answer is

= 10 - 3n

Hope this helps you.
