Write down the nth term of the following sequence:
7 2 -3 -8 -13
With steps and explanation please,!!

Answer :

Answer:

see explanation

Step-by-step explanation:

This is an arithmetic sequence with n th term

• [tex]a_{n}[/tex] = a + (n - 1)d

where a is the first term and d the common difference

d = 2 - 7 = - 3 - 2 = - 5 and a = 7, hence

[tex]a_{n}[/tex] = 7 - 5(n - 1) = 7 - 5n + 5 = 12 - 5n

[tex]a_{n}[/tex] = 12 - 5n ← n th term formula
