The recursive formula of the explicit rule an = (n + 1)² is 
where a1 = 4
<h3>How to determine the recursive formula?</h3>
The explicit formula is given as:
an = (n + 1)²
This means that:
a1 = (1 + 1)² = 4
a₂ = (2 + 1)² = 9
a₃ = (3 + 1)² = 16
Rewrite as:
a₂ = 4 + 2 * 2 + 1 = 9
a₃ = 9 + 2 * 3 + 1 = 16
Substitute a₂ = 9
a₃ = a₂ + 2 * 3 + 1 = 16
Express 2 as 3 - 1
a₃ = a₃₋₁ + 2 * 3 + 1
Express 3 as n
Evaluate the product
Hence, the recursive formula of the explicit rule an = (n + 1)² is where a1 = 4

Answer= 60
For both answers X= 60
Answer:
Oslo
Step-by-step explanation: -12 is below -5. Therefore it is colder the further below on the temperature
Answer: B 1/3
Step-by-step explanation:
For every 3x it travels 1 y so you will get 1/3 as your answer.
At 50y the line is at 10x. By the time it is at 60 y it is at 40x. This was a change in y by 10 and change in x by 30. There fore the answer is 10/30 or 1/3.
