Answer 1

• D) - 11

-----------------------------

Given three consecutive terms of a GP:

• 4, x + 3, 16

The middle term is the geometric mean of the other terms. Therefore:

• (x + 3)² = 4*16
• (x + 3)² = 64
• x + 3 = ± √64
• x + 3 = ± 8
• x = - 3 ± 8
• x = - 11 and x = 5

The matching choice is D.
