you must know that
term(n) = a + (n-1)d, where n is the term number, a is the first term and d is the common difference
so, for the first one:
n = 10, a = 1/2, d = 1/2
term(1) = 1/2 + 9(1/2) = 5
follow the same method for #2
#3 appears to have a typo, it is neither an arithmetic, nor a geometric sequence.
Did you mean: 5, 13, 21, 29 ??
then a = 5, d = 8
