Write a rule for the nth term of the arithmetic sequence. d =1/2 , a6 =18.

= n + 15

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₆ = 18 and d = , then

a₁ + 5d = 18 , that is

a₁ + = 18 ( subtract from both sides )

a₁ =

Thus

= + (n - 1) = + n - = n + 15

because its not ur topic and its not for is for homework not that.

d) 48
