Step-by-step explanation:

\huge{\red{\boxed{\boxed{\green{\underline{\red{\sf{SOLUTION-}}}}}}}}

a=-1

d=-1/2

To find:

A.P=?

a =  - 1 \\ d =  \frac{ - 1}{2}  \\  \\ a2 = a + d \\ a2 =  - 1 +  \frac{ - 1}{2}  \\ a2 =  \frac{ - 2 - 1}{2}  \\ a2 =   \frac{ - 3}{2}  \\  \\ a3 = a + 2d \\  a3 =  - 1 + 2 \times  \frac{ - 1}{2}  \\  a3 =  - 1 - 1 \\ 3 =  - 2 \\  \\ a4 = a + 3d \\ a4 =  - 1  + 3 \times  \frac{ - 1}{2}  \\ a4 =  - 1 +  \frac{ - 3}{2}  \\  a4 =  \frac{ -2 - 3}{2}  \\  a4 =  \frac{ - 5}{2}

\huge{\red{\boxed{\boxed{\green{\sf{A.P=-1,\frac{-3}{2},2,\frac{-5}{2}....}}}}}}
