Answer:
The sequence will be 4.15, 6.3, 8.45, 10.60, 12.75........
Step-by-step explanation:
The given sequence is 4.15, 6.3, 8.45
Now we check whether the given sequence is arithmetic of geometric.
6.3 - 4.15 = 2.15
8.45 - 6.3 = 2.15
There is a common difference of 2.15 which confirms it's an arithmetic sequence.
Explicit formula for the arithmetic sequence is

= nth term
a = first term of the sequence = 4.15
n = number of term
d = common difference = 2.15
Now we can find other terms of the sequence





Therefore, the sequence will be 4.15, 6.3, 8.45, 10.60, 12.75............
