Answer:
A
Step-by-step explanation:
Substitute n = 9 into the nth term rule
A(9) = - 15 + 2(9 - 1) = - 15 + 2(8) = - 15 + 16 = 1 → A
Answer:
7
Step-by-step explanation:
arithmetic sequence: aₙ = a₁ + (n-1)d
a₈ = (-5) + (8-1)d = 37
7d = 42
d = 6
a₃ = -5 + (3-1) x 6 = 7
I think it is 64 cause i multiplied
Answer:
This would be a trinomial.
Step-by-step explanation:
This is because X is number 1, b(y) is the second number, and -Z is the third.
In a trinomial, there are three numbers.
I hope this helps :)
The first one is D
The second one is true
