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.

CCABD are correct as of 2020
CCABD are still correct as of feb 24 2021
ccabd is still correct in 2022
Much love
CCABD Correct as of May 4th 2020
CCABD are still correct as of feb 2022
this is the nicest thread i’ve ever seen wth is with you ppl😐
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.
CCABD
CCABD are still the right choices for anyone who still needs to check their answers for the quiz in 2022!
Still correct tysm guys <3
Yessss I needed that ccabd
YASS TY BESTIEEE <3
still right now
What is the 15th term in the sequence using the given formula?
yn = 12n-1
CCABD is correct as far as november 2021
THANK YOU<3
Still correct!
still correct as of April 2022 🍓!!
They might've been forgotten by some, but not me. Thank you for your services o7
this is the best thread on this website so far everyone else just tries to trick you into doing the wrong answers.
Still correct!!!
STILL GOOD FEBRUARY OF 2023💝💖💌
it works as of march 2023
