Question

Find a formula for the nth term

Answer 1

Answer:

$a_{n}$ = - 1.3n - 2.4

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, thus

$a_{n}$ = - 3.7 - 1.3(n - 1) = - 3.7 - 1.3n + 1.3 = - 1.3n - 2.4
