3) Find the third, fifth, and seventeenth terms of the sequence described by each explicit formula.
a) a(n)= 8 + 3(n-1)
b) a(n)= 7 - 2(n-1)
c) a(n)= 3 + (n - 1)/2
d) a(n)= -9.2 - 2.5(n - 1)

For the rule of 78, for a 12-month period, the last term in the sequence is 12 and the series sums to 78. for an 10 month period, the last term is and the series sum is . for a 15 month period, the last term is and the series sum is . for a 20 month period, the last term is and the series sum is
