Question

Use geometric sequence formulas

Answer 1

Answer:

2nd term in the sequence is 2

2nd term in the sequence is 2 Step-by-step explanation:

As we know ,that in geometrical progression

As we know ,that in geometrical progression T(n) = arⁿ⁻¹

here , T(n) = Cₙ

• a = -6
• r = -1/3
• ∴ Cn = -6(-1/3)ⁿ⁻¹
• ∴ Cn = -6(-1/3)ⁿ⁻¹
• C₂ = -6(-1/3)²⁻¹
• C₂= -6×(-1/3)¹
• C₂ = 6×1/3
• C₂ = 2 Answer
