Question

pls answer this I can't get this question!!!​

Answer 1

Answer:

c = 3

Step-by-step explanation:

2ⁿ⁺² = 2ⁿ × 2² = 2ⁿ × 4

2ⁿ⁺¹ = 2ⁿ × 2

now, according to the question

2ⁿ⁺² - 2ⁿ⁺¹ + 2ⁿ = c × 2ⁿ

⇒ (2ⁿ × 4 - 2ⁿ × 2 + 2ⁿ)/2ⁿ = c

⇒ c = 2ⁿ × 4/2ⁿ - 2ⁿ × 2/2ⁿ + 2ⁿ/2ⁿ

⇒ c = 2ⁿ × 4 × 2⁻ⁿ - 2ⁿ × 2⁻ⁿ × 2ⁿ + 2ⁿ × 2⁻ⁿ

⇒ c = 4 - 2 + 1 = 3
