Answer:

see below

Step-by-step explanation:

100 - 91 = 9

91 - 82 = 9

82 - 73 = 9

we are subtracting 9 from each term

an+1 = an-9

or an = a1 + d (n-1) where an is the nth term, a1 is the 1st term d is the common difference and n is the term number

an = 100 -9(n-1)

an = 100 -9n+9

an = 109-9n
