Answer:

Rule:

a_n = 9^(n - 1)

8th term:

a_8 = 9^(8 - 1) = 9^7 = 4,782,969

Step-by-step explanation:

a_1 = 1 = 9^0

a_2 = 1 * 9 = 9^1

a_3 = 1 * 9 * 9 = 9^2

a_4 = 1 * 9 * 9 * 9 = 9^3

Notice that the exponent on the 9 is always 1 less than the number of the term.

Rule:

a_n = 9^(n - 1)

8th term:

a_8 = 9^(8 - 1) = 9^7 = 4,782,969
