Question

1.3 Consider the following number pattern and answer the questions that follow on canvas: 12; 21; 30; 39;... a) Fill in term number 7.​

Answer 1

66

Explanation:

`a_(n)` =
`a_(1)` + (n-1)d

`a_(n)` is the term that we are looking for. In this case,
`a_(7)`

`a_(1)` is the first term in the sequence. In this case, 12

n is the term that we are looking for. In this case, 7

d is the common difference. The sequence is going up by 9 each time

`a_(7)` = 12 + (7 - 1)9

`a_(7)` = 12 + 6(9)

`a_(7)` = 12 + 54

`a_(7)` = 66
