if in AP, if D=-4
and seventh term is 4 then we need to find a=?
according to question,
a+6d=4
a+6×-4=4
a+{-24}=4
a-24=4
a=4+24
a=28
hence the first term is 28
and seventh term is 4 then we need to find a=?
according to question,
a+6d=4
a+6×-4=4
a+{-24}=4
a-24=4
a=4+24
a=28
hence the first term is 28
