Step-by-step explanation:

as the formula of gradient is y²-y¹÷x²-x¹

so if we put this so tge answer cames 4

$\boxed{a_{n} = 250(0.4)^{n - 1}}\\$

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

$\boxed{a_{n} = 250(0.4)^{n - 1}}\\$
