Question

11th term of the AP: -3, -1/2, -2, . . . , is

Answer 1

Answer:

a₁₁ = 2

Step-by-step explanation:

i think your question is -3, -5/2, -2

first term = a = -3

common difference = d = a₃ - a₂ = -2 -(-5/2)

                                                     = -2 + 5/2

                                                     = -2 + 2.5

                                                     = 0.5

common difference = d = a₂ - a₁ = -5/2-(-3)

                                                     = -2.5 + 3

                                                     = 0.5

aⁿ =a+(n-1)d

a₁₁ = -3+(11-1)0.5

a₁₁ = -3+10*0.5

a₁₁ = -3+5

a₁₁ = 2
