Algebra 1 grade 9 can anyone me with these arithmetic sequence question? use this for the next 3 questions: consider the arithmetic sequence 3, -10, -23, - write an equation for the nth term of the sequence. an = find the 15th term in the sequence. a15 = which term of the sequence is -114?

1.  

2.  15th term is

3.  10th term is -114

Step-by-step explanation:

1.  The nth term of the sequence is given by the formula:

Here, the first term a = 3 and the common difference d = -10 - 3 = -13

So,

2.  To find the 15th term, put n = 15 in

= -179

Hence, the 15th term

3.  To find the term which is -114, put   in and solve for n.

-114 = 16 - 13n

13n = 16+114

13n = 130

n = 130/13

= 10

Hence, the tenth term is -114.

the answer is a
