Question

a=-7,d=1/2 write an A.P. whose first term is a and common difference is d

Answer 1

a1=-7
a2=a+d.
=-7+1/2
=-14+1/2

@2=-13/2

@3=a+2d
......=(-7)+2(1/2)
-=-7+1
=-8



hence Ap.... - 7,-13/2,-8.......

Answer 2

t1 = a = -7
t2 = t1 + d = -7 + 1/2 = -6.5
t3 = t2 + d = -6.5 + 1/2 = -6
t4 = t3 + d = -6 + 1/2 = -5.5
Hence, the given A.P. is -7,-6.5,-6,-5.5,.....
