Answer:
Use z = a +bi = IzI (cos (Ф) + i sin (Ф)) to find the trigonometric form. √2+∛ / 2 (cos (0) + i sin (0))
Step-by-step explanation:
The recursive formula of the geometric sequence is given by option D; an = (1) × (5)^(n - 1) for n ≥ 1
<h3>How to determine recursive formula of a geometric sequence?</h3>
Given: 1, 5, 25, 125, 625, ...
= 5
an = a × r^(n - 1)
= 1 × 5^(n - 1)
an = (1) × (5)^(n - 1) for n ≥ 1
