Hi Mate!!!
a5 = a + 4d and a3 = a + 2d
where a is ist term and d is common difference
a4 = a + 3 d = 4 equation 1
=> a5 - a3 = a + 4d - a - 2d = 4
=> 2d = 4
=> d = 2
Now, put value of d in equation 6
4 = a + 6
a = -2
So, ist term of A.p is -2
Have a nice time

how are you telling that 4= a+6??
Ok..... a5 - a3 = a4 ..... =. a + 4d - a - 2d = a + 3d...........= 2d = a + 3d. where d = 2 a + 3( 2 ) = 2(2)..... a + 6 = 4
