$\huge\sf\purple{Steps}$

To get the terms of A.P, either follow the standard form of A.P

That is,

❍ (a + d), (a + 2d) and (a + 3d).

❍ Or simply add common difference to the first term, and then proceed with the resulting number.

$\underline{\bullet{\sf{\;Method \:1}}}$

a₁ = - 5

a₂ = - 5 + 0.5 = - 4.5

a₃ = - 4.5 + 0.5 = - 4

a₄ = - 4 + 0.5 = - 3.5

$\underline{\bullet{\sf{\;Method \:2}}}$

a₂ = - 5 + 0.5 = - 4.5

a₃ = - 5 + (2 ×0.5) = - 5 + 1 = -4

a₄ = - 5 + (3 ×0.5) = - 5 + 1.5 = -3.5
