Answer 1

Answer:

hey friend hope it will help you

Step-by-step explanation:

This is clearly an arithmetic sequence because the terms differ by 2 each time.

To find the nth term rule we need:

a value for the first term , a

and a value for the common difference d .

These values are then plugged into the formula:

T

n

=

a

+

(

)

d

a

=

1

and

d

=

2

n

=
