1. The explicit formula an = 2-5 (n-1) represents an arithmetic sequence. Write the recursive formula for the sequence.

Lesson 4: Formulas for Arithmetic Sequences

1. d
2. a,f
3. b

star four! is 100% CORRECT

Star four! is still correct as of 2020 :)

Star four is still correct as of today.

1.D
2.A.F
3.B

since 5(n-1) subtracts 5 when n increases by 1,

a_n = a_(n-1) - 5
now, what is a_1 ?

star four still correct 10/15/21

still correct 10/19/2021

d, af, b is still correct

yep its right

Star four! is still correct in 2022.
