Arithmetic And Geometric Progression
1 Arithmetic Progression (AP)
1.1 a - First term
1.2 d - Common difference
1.3 Tn - nth term of AP
1.4 Tn = a + (n-1)d
1.5 Sn = (n/2) (2a + {n-1}d)
1.5.1 Sn = (n/2) (a + Tn)
1.5.2 Sn = (n/2) (a + l)
1.6 l = Last term of Ap
2 Geometric Progression (GP)
2.1 a = First term
2.2 r = ratio
2.3 Tn = a * r^(n-1)
