Question

Please help with questions 1d and e

Answer 1

Explanation:

one- one- one direction

Answer 2

(d)
`(75)/(2)`,
`(75)/(4)`,
`(75)/(8)`

(e) 68, 82, 96

(d) note that the terms have a common ratio ( r )

r =
`(300)/(600)` =
`(150)/(300)` =
`(1)/(2)`

to obtain any term in the sequence, multiply the previous term by
`(1)/(2)`

75 ×
`(1)/(2)` =
`(75)/(2)`

`(75)/(2)`×
`(1)/(2)` =
`(75)/(4)`

`(75)/(4)` ×
`(1)/(2)` =
`(75)/(8)`

(e) note that the terms have a common difference (d )

d = 26 - 12 = 40 - 26 = 54 - 40 = 14

to obtain any term in the sequence, add 14 to the previous term

54 + 14 = 68

68 + 14 = 82

82 + 14 = 96
