Answer:
= n - 2
Step-by-step explanation:
Note the difference between consecutive terms is constant, that is
0 - (- 1) = 0 + 1 = 1
1 - 0 = 1
2 - 1 = 1
3 - 2 = 1
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 1 and d = 1, thus
= - 1 + n - 1 = n - 2
1)-6/4x+4
2)-5/3x
3)3x+2
4)3/2x+3
5)0x-1
6)1/2x+2
7)3x+4
8)-1/3x
I added some guides for you to know how to do this.
