Answer:
Here's what I get
Step-by-step explanation:
aₙ is the nth term in the arithmetic sequence and aₙ₋₁ is the term that comes immediately before it in the sequence.
We know that a₅ = 23. To find a₈, we must find a₆ and a₇.
a₅ = 23
a₆ = a₅ + 5 = 23 + 5 = 28
a₇ = a₆ + 5 = 28 + 5 = 33
a₈ = a₇ + 5 = 33 + 5 = 38
2x⁴ + 4x² + 6x⁹ - x + 3x⁹ - 5x⁹ + 2x⁸
2x⁴ + 4x² + 6x⁹ + 3x⁹ - 5x⁹ - x + 2x⁸
2x⁴ + 4x² + 4x⁹ - x + 2x⁸
-4x⁹ - 2x⁸ - 2x⁴ - 4x² - x
