Could someone check my work;
1. Generate the first five terms in the sequence using the explicit formula.
yn = –5n – 5
–30, –25, –20, –15, –10
30, 25, 20, 15, 10
–10, –15, –20, –25, –30(my answer)
10, 15, 20, 25, 30
2. What is the 15th term in the sequence using the given formula?
cn = 3n – 1
14
57
44
–44(my choice)
3. Write a recursive formula for the sequence 7, 13, 19, 25, 31, ... Then find the next term.
an = an– 1 + 6, where a1 = 7; 37(my choice)
an = an– 1 + 6, where a1 = 37; 7
an = an– 1 – 6, where a1 = 6; –23
an = an– 1 – 6, where a1 = 7; –8
4. Write a recursive formula for the sequence 7, 4, 1, –2, –5, .... Then find the next term.
an = an–1 – 3, where a1 = –8; 7
an = an–1 – 3, where a1 = 7; –8(my answer)
an = an–1 + 3, where a1 = –3; 22
an = an–1 + 3, where a1 = 7; –8
5. Write an explicit formula for the sequence 8, 6, 4, 2, 0, ... Then find a14.
an = –2n + 10; –16
an = –2n + 8; –18
an = –2n + 8; –20
an = –2n + 10; –18
Dont understand this problem.

Reiny
your first four are correct
#5.
In the explicit formula, you can find any term directly , unlike a recursive, where you have to know the previous term
so if n = 1, we should get 8 from the formula
look at the first and last
the both give you
a(1) = 2(1) = 10 = 8
a(14) = 2(14) + 10 = 28+10= 18
so it has to be the last one.

Why would you attempt to give wrong answers when there is multiple people saying that other was correct? People are hella f**cing dumb.
