a)15
b)7
c)11
d) -256
given,
term=a8
a) For the sequence {an} with the term an = 2n - 1, the term a8 equals 2(8) - 1 = 16 - 1 = 15.
b) For the sequence {an} with the term an = 7, the term a8 equals 7, as all terms in the sequence are the same.
c) For the sequence {an} with the term an = 1(-1)^n, the term a8 equals 1(-1)^8 = 1(1) = 1.
d) For the sequence {an} with the term an = -(-2)^n, the term a8 equals -(-2)^8 = -(256) = -256.
