An arithmetic sequence is represented by the explicit formula A(n) = 2 +(n − 1)(− 5)
2 answers:
Answer:
=
- 5
Step-by-step explanation:
Given the explicit formula
A(n) = 2 - 5(n - 1)
Compare with the standard form
A(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 5
A recursive formula allows a term in the sequence to be found by adding d to the previous term.
Then recursive formula is
=
- 5 , with a₁ = 2

- To solve this equation, the first step is to add the numbers 9.5 + 6.2 into the equation and it will lead to 15.7 as the number for step one.
- To solve this equation, the second step is to subtract the numbers 15.7 - 12.25 into the equation and it will lead to 3.45 as the answer.
- To solve this equation, the third step is to multiply the numbers 8.6 x 3.45 into the equation and it will lead 29.67 as the final answer for the whole equation.
