Step-by-step explanation:

this is because think of it as walking up the stairs, you walk up 3 steps and turn around and walk down 3 more, therefore you climb 15 feet up and climb the same amount of feet back down

An arithmetic sequence has the recursive structure

$a_n=a_{n-1}+d$

and can be solved explicitly for the

term,

, in terms of the first term of the sequence a_1

.

$a_n=a_{n-1}+d$
$\implies~a_n=a_{n-2}+2d$
$\implies~a_n=a_{n-3}+3d$
$\implies\cdots\implies a_n=a_1+(n-1)d$

You know the 100th term of the sequence is $a_{100}=1000$ and that the common difference between terms is d=5

, which means you have enough information to find the first term:

$a_{100}=a_1+(100-1)\times5\implies1000=a_1+99\times5\implies a_1=505$
