A) $2.1,2.8,3.5,4.2,4.9$
B) $1.4,0.7,0 , - 0.7 , - 1.4$
C) $0.7,0 , - 0.7 , - 1.4 , - 2.1$
D) $1.4,2.1,2.8,3.5,4.2$

The first term is 1.4, and each subsequent term increases by the common difference of 0.7. Therefore, the sequence is 1.4, 2.1 (1.4+0.7), 2.8 (2.1+0.7), 3.5 (2.8+0.7), 4.2 (3.5+0.7).
