Find the 7th term of the arithmetic sequence given a1 = -12 and d=2
Answers
GPT 3.5
To find the 7th term of an arithmetic sequence, we can use the formula:
a_n = a_1 + (n-1)d
where a_n is the nth term, a_1 is the first term, n is the position of the term, and d is the common difference.
In this case, a_1 = -12 and d = 2.
Plugging these values into the formula, we have:
a_7 = -12 + (7-1)(2)
= -12 + 6(2)
= -12 + 12
= 0
Therefore, the 7th term of the arithmetic sequence is 0.
a_n = a_1 + (n-1)d

Plugging these values into the formula, we have:

= -12 + 12
= 0
Therefore, the 7th term of the arithmetic sequence is 0.
