Answer:
c.) aₙ = 5 × 4ⁿ⁻¹
Explanation:
Geometric sequence: aₙ = a(r)ⁿ⁻¹
where 'a' resembles first term of a sequence, 'r' is the common difference.
Here sequence: 5, 20, 80, 320,...
First term (a) = 5
Common difference (d) = second term ÷ first term = 20 ÷ 5 = 4
Hence putting into equation: aₙ = 5(4)ⁿ⁻¹

A. y = 2x - 3
This is the correct answer
54 is 75% of x.
75% of x:

75% of x is (3/4)x and 75% of x is 54. Set (3/4)x equal to 54:

54 is 75% of
