Formulas and Key Relations

Arithmetic Progression Formulas

T_n = a + (n-1)d

l = a + (n-1)d

l - (n-1)d

S_n = n/2 {2a+(n-1)d}

Geometric Progression Formulas

r = T_2/T_1 = T_3/T_2 = ... = T_n/T_(n-1)

l / r^(n-1)

b/a = c/b => b^2 = ac

S_n = a(1-r^n)/(1-r)

The nth term of an A.P. is Tn = a + (n-1)d.
