Answer:

an = 4 • -1^n

Step-by-step explanation:

Substitute in the value of  n  to find the  n th term.

a 2 = 4 ⋅ ( − 1 2 )  One to any power is one.  a 2 = 4 ⋅ ( − 1 ⋅ 1 )

Multiply  − 1  by  1 .

a 2 = 4 ⋅ − 1

Multiply  4  by  − 1 .

a 2 = − 4

-65536

-1 x 4= -4

-4 x 4= -16

-16 x 4= -64

-64 x 4= -256

-256 x 4= -1024

-1024 x 4= -4096

-4096 x 4= -16384

-16384 x 4= -65536

tino4ka555 [31]
Y - y1 = m(x - x1)
slope(m) = 6/7
(-9,6)....x1 = -9 and y1 = 6
now we sub...pay close attention to ur signs
y - 6 = 6/7(x - (-9)....not done yet
y - 6 = 6/7(x + 9) <===

Given the first three terms of a linear sequence: 3x – 2;x+9; 2x + 5 Determine the value of x.​
Yuliya22 [10]

Answer:

x = 5

Step-by-step explanation:

The difference between consecutive terms will be equal , then

a₂ - a₁ = a₃ - a₂ , that is

x + 9 - (3x - 2) = 2x + 5 - (x + 9) ← distribute parenthesis on both sides

x + 9 - 3x + 2 = 2x + 5 - x - 9 , simplify both sides

- 2x + 11 = x - 4 ( subtract x from both sides )

- 3x + 11 = - 4 ( subtract 11 from both sides )

- 3x = - 15 ( divide both sides by - 3 )

x = 5
