Answer:
Step-by-step explanation:
Step 1. Calculate the common ratio
a₁ = 250
a₂ = 100
a₃ = 40
a₄ = 16
The common ratio is
a₃/a₂ = 40/100 = 0.4
Step 2. Write the formula for the series
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
Thus, the formula for the series is
Answer:
4^3/2 = 8; 4^y = 8^6
Step-by-step explanation:
4^3 = 64
64^1/2 = 8
4^3/2 = 8
Part 2:
4^y = 8^6
y = 9
It will be written in this form
