A1 = 4
a2 = 5a1 = 5 x 4 = 20
a3 = 5a2 = 5 x 20 = 100
a4 = 5a3 = 5 x 100 = 500
a5 = 5a4 = 5 x 500 = 2,500
Tn = ar^(n-1); where a = 4, r = 5
Tn = 4(5)^(n-1) = 4/5 (5)^n
Explicit formular is Tn = 4/5 (5)^n

Answer:
26.3 m
Step-by-step explanation:
The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.
We solve the above question using Pythagoras theorem
c² = a² + b²
Where
c = Longest part of the triangle = 37 m
a = Height of the triangle = ?
b = Length of the shadow = 26 m
Hence:
37² = a² + 26²
a² = 37² - 26²
a = √37² - 26²
a = √(693)
a = 26.324893162m
Approximately = 26.3 m
