In a sequence of numbers, every number, except for the first one, is four times the square of a previous number. If the first number in the sequence is T, which of the following represents the value in terms of T, of the third number after the first number?
A. \(4^3T^4\)
B. \(4^4T^4\)
C. \(4^6T^8\)
D. \(4^7T^8\)
E. \(4^8T^8\)
Each term = 4(previous term squared)
term1 = T
term2 = 4(T²) = 4T²
term3 = 4[(4T²)²] = 4(4²T⁴) = 4³T⁴
term4 = 4[(4³T⁴)²] = 4(4⁶T⁸) = 4⁷T⁸
Answer: D
