Question

Write a rule for the sequence. then, find the unknown term 2.1, 4.3, 6.5, ..., 10.9

Answer 1

8.7

Explanation:

I'm assuming you want the term between 6.5 and 10.9

The sequence is aritmetic with a

common difference of 6.5 - 1.3 = 4.3 - 2.1 = 2.2

6.5 + 2.2 = 8.7

Answer 2

8.7

All the first digits are even numbers..and the numbers behind the decimal points are odd numbers
