Answer:

  • 25 - 10n
  • 15 - 10(n - 1)

Explanation:

sequence: 15, 5, -5, -15, -25

solve:

1st rule 25 - 10n:

25 - 10(0) = 15

25 - 10(2) = 5

25 - 10(3) = -5

25 - 10(4) = -15

25 - 10(5) = -25

second rule using 15 - 10(n - 1):

15 - 10(1 - 1) = 15

15 - 10(2 - 1) = 5

15 - 10(3 - 1) = -5

15 - 10(4 - 1) = -15

15 - 10(5 - 1) = -25
