Formula Sheet — Progressions and Series

Important formulas and equations from Progressions and Series for CMAT Quantitative Techniques & Data Interpretation.

Formulas — Progressions and Series

Arithmetic Progression (A.P.)

Tn = a + (n-1)d
Sn = n/2[2a + (n-1)d]
Sn = n/2(a + l)
d = (Tm - Tn)/(m - n)

Geometric Progression (G.P.)

Tn = ar^(n-1)
Sn = a(r^n - 1)/(r - 1) when r > 1
Sn = a(1 - r^n)/(1 - r) when r < 1
S∞ = a/(1-r) when |r| < 1
G = √(ab)

Harmonic Progression (H.P.)

H = 2ab/(a + b)

Means Relationship

A·H = G²
