Answer 2

according to question    its 4th term is 1 i.e        a+3d=1...................{1}
                                      its 8th term is 2 i.e        a+7d=2....................{2}
a+3d=1
a+7d=2
solving {1} and{2}-
from {1}
a=1-3d.......................{3}
puttin the value of {3} in {2}-
1-3d+7d=2
1+4d=2
4d=1
d=1/4
putting te value in {3} we get,
you also get a=1/4

for 10th term-    a+9d
                         1/4+9×1/4
                           10/4=5/2 ans
