So you know that for arithmetic sequences, the difference between each term is the same. So we can use this to form an equation:
Difference between term 2 and 1 = Difference between term 3 and 2
So the three values are:
<u>
</u>5, 0.5(5)+7, 3(5)-1
= <u>5, 9.5, 14</u>
Difference between term 2 and 1 = Difference between term 3 and 2
So the three values are:
<u>
</u>5, 0.5(5)+7, 3(5)-1
= <u>5, 9.5, 14</u>
