First term: a(1) = 4; common ratio: r = 2

Then:

a(n) = 4(2)^(n-1)

Check: Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32 (correct)

What is the value of k?

Molodets [167]

Answer:

$( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12$
