Question

Which equation represent the nth term of the arithmetic sequence?

Answer 1

Answer:

        D.   aₙ = 5n - 11

Step-by-step explanation:

The equation of the nth term of the arithmetic sequence is: $a_n =a_1+d(n-1)$

d = 9 - 4 = 5

a₁ = -6

Therefore:

               $a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11$
