Work Step by Step
a) A sequence is a list of numbers, and they are written in order. Each number is a "term" and are denoted $a_1, a_2, a_3, a_4...$
b) The even numbers are divisible by 2 and can be written $a_n=2n$ and odds can be written as the even numbers plus 1.
$a_n = 2n+1$
c) $a_1 = 1/2, a_2 = 2/3, a_3=3/4, a_{10}=10/(10+1) = 10/11$
