You have to take the 3 and multiply what ever is in the parenthasis so 3*4 is 12 but you cant mutliply x so its 12x and them 3*3 is 9 so your answer would be 12x+9

Find the pattern and use it to list the next two terms in the sequence.

lidiya [134]

Answer:

Step-by-step explanation:

a₁ = -3 = (-1)¹×3

a₂ = 6 = (-1)²×2×3

a₃ = -28 = (-1)³×2²×7

a₄ = 72 = (-1)⁴×2³×3²

a₅ = -360 = (-1)⁵×2³×3²×5

a₆ = 2160 = (-1)⁶×2⁴×3³×5

That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.
