What is the 7th number in the following pattern: 3.2, 4.4, 5.6, 6.8, ...

This is an arithmetic sequence with an increase amount of 1.2. Each term S(n) is found by adding 1.2 to the prior term.
S(1) = 3.2
S(2) = 3.2 + 1.2 = 4.4
S(3) = 4.4 + 1.2 = 5.6
S(4) = 5.6 + 1.2 = 6.8
S(5) = 6.8 + 1.2 = 8.0
S(6) = 8.0 + 1.2 = 9.2
S(7) = 9.2 + 1.2 = 10.4
