How to rearrange text file via awk?

I wanna print field (from 4th to the last field) as new line for each by inserting increasing arithmetically variable (from 5 to 25) after 3rd field in the text file.

Data format:

01.01.1995 01:00 1.0 1.2 2.5 3 4.8 5.231.01.1995 23.00 31.0 2.3 7.5 8.7 8.7 10

.

awk '{for(i=5;i<=25;i+=5) print $1,$2,$3,i,$(3+i/5)}'

Desired output:

01.01.1995 01.00 1.0 5 1.201.01.1995 01.00 1.0 10 2.501.01.1995 01.00 1.0 15 301.01.1995 01.00 1.0 20 4.801.01.1995 01.00 1.0 25 5.231.01.1995 23.00 31.0 5 2.331.01.1995 23.00 31.0 10 7.531.01.1995 23.00 31.0 15 8.731.01.1995 23.00 31.0 20 8.731.01.1995 23.00 31.0 25 10

Desired output 2:

01.01.1995 01.00 1.0 5 5.201.01.1995 01.00 1.0 10 4.801.01.1995 01.00 1.0 15 301.01.1995 01.00 1.0 20 2.501.01.1995 01.00 1.0 25 1.231.01.1995 23.00 31.0 5 1031.01.1995 23.00 31.0 10 8.731.01.1995 23.00 31.0 15 8.731.01.1995 23.00 31.0 20 7.531.01.1995 23.00 31.0 25 2.3

So the first three field should be same.
