Step-by-step explanation:
According to congruent chords and arcs theorem, if then
.
This means that
Thus:
(full circle = 360°)
Plug in the values into the equation
Add like terms
Subtract 36 on both sides
Divide both sides by 12
Imagine a corner of a cube.

well, the recursive rule of aₙ = aₙ₊₁ + 7, where a₁ = 15, is simply saying that
we start of at 15, and the next term is obtained by simply adding 7, and so on.
well, that's the recursive rule.
so then let's use that common difference and first term for the explicit rule.
