an 126, 3,725

Part A: What is the first term, a1, of the sequence? (2 points)
Part B: What is the general term equation, an, for this sequence? (1 point)
Part C: What is the value of the 13th term of this sequence? (1 point)

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
