Answer 1

a. U1 = 1² - 2(1) = -1

U2 = 2² - 2(2) = 0

U3 = 3² - 2(3) = 3

U4 = 4² - 2(4) = 8

U5 = 5² - 2(5) = 15

U6 = 6² - 2(6) = 24

U7 = 7² - 2(7) = 35

tujuh suku pertama: -1, 0, 3, 8, 15, 24, 35, ...

b. U1 = 1 / (1) + 3 = 1/4

U2 = 1 / (2) + 3 = 1/5

U3 = 1 / (3) + 3 = 1/6

U4 = 1 / (4) + 3 = 1/7

U5 = 1 / (5) + 3 = 1/8

U6 = 1 / (6) + 3 = 1/9

U7 = 1 / (7) + 3 = 1/10

tujuh suku pertama: 1/4, 1/5, 1/6, 1/7, 1/8, 1/9, 1/10, ...

c. U1 = (1) / (1)² + 1 = 1/2

U2 = (2) / (2)² + 1 = 2/5

U3 = (3) / (3)² + 1 = 3/10

U4 = (4) / (4)² + 1 = 4/17

U5 = (5) / (5)² + 1 = 5/26

U6 = (6) / (6)² + 1 = 6/37

U7 = (7) / (7)² + 1 = 7/50

tujuh suku pertama: 1/2, 2/5, 3/10, 4/17, 5/26, 6/37, 7/50, ...
