Question

Write a linear equation that represents the arithmetic sequence 10, 8, 6, 4, ...

Answer 1

Answer:

A

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = 8 - 10 = - 2, thus

$a_{n}$ = 10 - 2(n - 1) → A
