a sequence has a first number of 3 and a half common difference of 4 what is the recursive rule of nth term

for

Step-by-step explanation:

Given

-- First Term

--- half common difference

Required

Find the recursive rule

First, we calculate the common difference

Multiply through by 2

The second term of the sequence is:

The third term is:

So, we have:

Substitute f(1) for 3

Express 1 as 2 - 1

Substitute n for 2

Similarly:

Substitute f(2) for 11

Express 2 as 3 - 1

Substitute n for 3

Hence, the recursive is:

for

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
