Question

1. Generate the first five terms in the sequence using the explicit formula.
yn = –5n – 5
(1 point)
–30, –25, –20, –15, –10
30, 25, 20, 15, 10
–10, –15, –20, –25, –30
10, 15, 20, 25, 30
2. What is the 15th term in the sequence using the given formula?
cn = 3n – 1 (1 point)
14
57
44
–44
3. Write a recursive formula for the sequence 7, 13, 19, 25, 31, ... Then find the next term.
(1 point)
an = an– 1 + 6, where a1 = 7; 37
an = an– 1 + 6, where a1 = 37; 7
an = an– 1 – 6, where a1 = 6; –23
an = an– 1 – 6, where a1 = 7; –8

Answer 1

for the first one just plug in 1 , 2 ,3 4,5 instead of n in the formula for yn

Answer 2

- that makes the first term -5*1 - 5
