Question

Answer each question about the following series: 3 4.5 6 7.5 9 10.5. what is the common difference of the arithmetic sequence on which the series is based? d =

Answer 1

45.6

Explanation:

Answer 2

1.5

Explanation:

In the given series 3 4.5 6 7.5 9 10.5

`a_(1)=3` ,
`a_(2)=4.5` ,
`a_(3) =6`

As the series is arithmetic and in arithmetic series common difference is,

`d=a_(2)-a_(1)`

`d_(1) =4.5-3=1.5\\`

`d_(2) =6-4.5=1.5`

So, common difference is 1.5
