Question

20 POINTS! Find an equation for the nth term of the sequence. -1, -4, -16, -64, ...

Answer 1

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

Answer 2

-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
