PLEASE HELP!!

n + 3 (n -2) = 10.4

n=4.15

Step-by-step explanation:

cross multiply:

n+3n-6=10.4

add like terms:

4n-6=10.4

cancel 6 by adding 6 to both sides

4n = 16.4

divide by 4 to isolate n

n=4.15

Sequences are usually defined as a function with a domain in the set of positive integers. the terms of the sequence are usually denoted as  ,  ,    . it is defined the way it is so that the "first" term would correspond to n = 1, the "second" term would correspond to n = 2, and so on.  these would be based on the apparent terms, terms enumerated based on what we see.that is the gist of why the answer is "all integers where n  ≥ 1"we do not include "0" because there is not a zeroth term when we are relying on apparent terms
