101 - Percentage decrease =
101 - (43% × 101) =
101 - 43% × 101 =
(1 - 43%) × 101 =
(100% - 43%) × 101 =
57% × 101 =
57 ÷ 100 × 101 =
57 × 101 ÷ 100 =
5,757 ÷ 100 =
57.57
Answer:
- 5, 2, 9, 16 and d = + 7
Step-by-step explanation:
to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula
f(1) = - 5 ← given
f(2) = f(1) + 7 = - 5 + 7 = 2
f(3) = f(2) + 7 = 2 + 7 = 9
f(4) = f(3) + 7 = 9 + 7 = 16
common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7
