Find a formula for the nth term
of the arithmetic sequence.
First term -3.7
Common difference -1.3

Respuesta :

Answer:

[tex]a_{n}[/tex] = - 1.3n - 2.4

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference, thus

[tex]a_{n}[/tex] = - 3.7 - 1.3(n - 1) = - 3.7 - 1.3n + 1.3 = - 1.3n - 2.4
