Question

Find the formula for the nth term in this arithmetic sequence a1=0 a2=.5 a3=1 a4=1.5

Answer 1

Answer:

Step-by-step explanation:

The arithmetic sequence usually write as $a_{n}=a_{1} +(n-1)d$, where a1 is the first term and d is a common difference.

$a_{n} = a_{1}+(n-1)d\\a_{n} = 0+(n-1)0.5$
