Explanation:

Step1: Substitute a=8, b=2

$a + b = 8 + 2 = 10$

Step2: Substitute b=2, c=$\frac{1}{2}$

$b + c = 2 + \frac{1}{2} = \frac{5}{2}$

Step3: Substitute a=8, b=2

$ab = 8 \times 2 = 16$

Step4: Substitute c=$\frac{1}{2}$, a=8

$ca = \frac{1}{2} \times 8 = 4$

Step5: Substitute a=8

$4a = 4 \times 8 = 32$

Step6: Divide 14 by 2

$\frac{14}{2} = 7$

Step7: Identify geometric sequence (×2)

$8 \times 2 = 16$, $16 \times 2 = 32$, $32 \times 2 = 64$

Step8: Calculate sum of 8 and 7

$8 + 7 = 15$

Step9: Calculate difference of 9 and 3

$9 - 3 = 6$

Step10: Follow order of operations (multiply first)

$10 - 3 \cdot 3 = 10 - 9 = 1$
