A.P. (monday to saturday= 6 days)
mon - a
tue- a+d
wed- a + 2d
thu - a+3d
fri - a+4d
sat - a+ 5d
wed- a+2d = -30
a= 30-2d
sum of temp. of tue and sat -
(a+d) + (a+5d)
mon - a
tue- a+d
wed- a + 2d
thu - a+3d
fri - a+4d
sat - a+ 5d
wed- a+2d = -30
a= 30-2d
sum of temp. of tue and sat -
(a+d) + (a+5d)
a+d+a+2d
2a+3d
mon & sat. a + a+5d = 2a=5d
2a+5d = 5 +2a +3d
inserting value of a = 30-2d
2(30-2d) +5d = 2(30-2d) +5 +3d
60-4d +5d = 60 -4d +3d +5
d= 5-d
