Answer 2

Step-by-step explanation:

An = a + (n-1)d

i) An = 7 + (8-1)3

= 7 + 7*3

= 7 + 21

= 28

ii) 0 = -18 + (10-1)d

18 = 9d

d = 18/9 = 2

iii) -5 = a + (18-1)(-3)

-5 = a + 17(-3)

-5 = a - 51

a = -5 + 51 = 46

iv) 3.6 = -18.9 + (n-1)(2.5)

22.5 = 2.5(n - 1)

9 = n - 1

n = 10

v) An = 3.5 + (105-1)(0)

An = 3.5 + 104 * 0

An = 3.5 + 0 = 3.5
