Question

Question 12 (1 point) Johnny says the sequence below is (A) Arithmetic because it has a common difference. He also says the first term is 100. (B) Do you agree? a 65 – 100n (A) Is it arithmetic? (B) is the first term 1007 if not what is the first term?​

Answer 1

The sequence is Arithmetic because it uses subtraction.

The first term is a(1) = 65 since it comes first in the formula.

Explanation:

We are given the equation 65-100n. 65 is the first term since it comes first in the arithmetic formula and 100n is the common difference. So the correct answer should be an arithmetic sequence and 65 as the first term.

I also got it right when i took the test :)
