Liberty Zhang · Answer 1

In an arithmetic series, the value of the nth term is calculated using the equation,

an = ao + (n - 1) (d)

where an and ao are the nth and the 1st term, respectively. d is the common difference, and n is the number of terms.

In the given, an = 48, a0 = 93, d = - 5 and n is unknown. Substituting the known values,

48 = 93 + (n - 1) (-5)

The value of n from the equation is 10. Thus, the answer is the last choice.
