Answer:
a+5d = 7 **
a+5d = 7 **a+ 3d = 2(a+d) - 1
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1
a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **
