Answer:
y=3x+15
Step-by-step explanation:
y2-y1 6 - 3 3
_____= _______= ______= 3
x2- x1 -3 + 4 1
y - y1 = m(x - x1)
= y -6 = 3( x + 3)
= y -6 = 3x + 9
= y = 3x + 15
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
