The order of the twelve solar terms

Answer:

Using the nature of arithmetic progression

Then S4, S8-S4, S 12-S8, S 16-S 12, S20-S 16 become arithmetic progression with a tolerance of d.

That is1414+d14+2d14+3d14+4d.

S4= 14。

S20-S8

=(s 12-S8)+(s 16-s 12)+(S20-s 16)

=42+9D

∴ 42+9D=30

∴ D=- 12/9=-4/3

∴S8 = S4+(S8-S4)= 14+ 14+d = 28-4/3 = 80/3
