The three numbers have no prime divisors in common:
So, the least common multiple is the product of the numbers:
6.39 :) because in the tenths place there is a 3 and the six rounds that up to a 4!
Answer:
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
Step-by-step explanation:
a₁ = 75
a₂ = 75 x 0.2¹ = 75 x 0.2 ²⁻¹ = 15
a₃ = 75 x 0.2² = 75 x 0.2³⁻¹ = 3
.......
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
