Answer:
The given sequence is an arithmetic sequence having a common difference of 2.15.
Step-by-step explanation:
The given sequence is 4.15, 6.3, 8.45,.....
In the given sequence pattern may be either arithmetic or geometric.
For Arithmetic Sequence,
There should be a common difference in each successive term of the sequence.
[tex]T_{2}-T_{1}=T_{3}-T_{2}[/tex]
[tex]T_{2}-T_{1}=6.3-4.15[/tex]
[tex]T_{2}-T_{1}=2.15[/tex]
[tex]T_{3}-T_{2}=8.45-6.3[/tex]
[tex]T_{3}-T_{2}=2.15[/tex]
Therefore, the given sequence is an arithmetic sequence having a common difference of 2.15.
