Formula: 

Geometric Mean = ((X
₁)(X₂)(X₃)........(Xₙ))^1/ⁿ
Where, 
X = Individual score 
N = Sample size (Number of scores)
The geometric mean is defined the nth root of the product of n number. The formular is given as n√ a1 * a2 * a3 * ... where an are the the values of the sample. Here there are 2 numbers so n = 2 Our geometric mean = 2√ 18 * 2 = 2 √36 = √36 = 6
