STUDY CARD 1
Kjerneoppskrift for induksjonssteget ($n = k + 1$):
$$\text{VS for } (n = k + 1) = \underbrace{\Big( \text{Ledd}_1 + \text{Ledd}_2 + \dots + \text{Ledd}_k \Big)}_{\text{Dette erstattes med HS for } n=k} + \underbrace{\text{Ledd}_{k+1}}_{\text{Nytt ledd fra VS med } (k+1)}$$
STUDY CARD 2
Uendelig geometrisk rekke
$$S = \frac{a_1}{1 - k}$$
STUDY CARD 3
Summen - Aritmetisk rekke
$$S_n = \frac{n \cdot (a_1 + a_n)}{2}$$
STUDY CARD 4
Konvergent geometrisk rekke
$$S = \frac{a_1}{1 - k}$$
STUDY CARD 5
Geometrisk (Eksplisitt)
$a_n = a_1 \cdot k^{n-1}$
STUDY CARD 6
Geometrisk (Rekursiv)
$a_n = k \cdot a_{n-1}$
