Give the next two terms for the given Arithmetic sequence given the firsts term and the common difference. Given a1=1/2 , d=-2/3 Solve for a2 and a3

Answer 1

a₁ = 1/2

a₂ = 1/2 - 2/3 = -1/6

a₃ = -1/6 - 2/3 = -5/6

Answer 2

a1=.5, a2=1, a3=1.5

d=-.66 d=-1.33 d=-2

Answer 3

a2 = 1/2 + (2-1) * (-2/3)

a2 = -1/6

a3 = 1/2 + (3-1) * (-2/3)

a3 = -5/6
