Question

If the sequence t₁, t₂, t₃ … is in A.P. then the sequence t₆, t₁₂, t₁₈ … is

Options

• a Geometric Progression

• an Arithmetic Progression

• neither an Arithmetic Progression nor a Geometric Progression

• a constant sequence

Answer 1

an Arithmetic Progression

Explanation;

Hint:

If t₁, t₂, t₃, … is 1, 2, 3, …

If t₆ = 6, t₁₂ = 12, t₁₈ = 18 then 6, 12, 18 … is an arithmetic progression
