Find an equation for the nth term of the arithmetic sequence.

-15, -6, 3, 12,

an = -15 + 9(n + 1)
an = -15 x 9(n - 1)
an = -15 + 9(n + 2)
an = -15 + 9(n - 1)

Step-by-step explanation:

The terms of the arithmetic sequence are...

-15, -6, 3, 12, ...

The first term is

a_1=-15

The common difference is

The equation for the nth term is given by;

We substitute the values into the formula to get;

D

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a + (n - 1)d

where a is the first term and d the common difference

d = - 6 - (- 15) = - 6 + 15 = 9, and a = - 15

= - 15 + 9(n - 1)

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
