<u>Answer</u>
101
<u>Explanation</u>
Let the first term of the sequence to be a.
1st term = a
2nd term = a+1
3rd term = a+2
4th term = a+3
5th term =a+4
a+(a+1)+(a+2)+(a+3)+(a+4)=505
5a+10=505
5a=505-10
5a=495
a=99
3rd term = a+2
=99+2
= 101

Answer: 27,24,21....
d=24-27=-3 a=27
let nth term=0

(n-1)-3=-27
n-1=9
n=10
Step-by-step explanation:
Zack reads faster so he will finish first
