Answer: D) 8-------------------------
The number outside the (n-1) term, which is 8, is the common difference. It tells us how much to increment by each time. In this case, the next term is found by adding 8 onto the previous term. That's exactly what

is saying.
Answer:
the speed of light in miles per year is 5.88 × 10^12 mi / year
Step-by-step explanation:
The computation of the speed of light in miles per year is shown below;
As we know that
1 m/sec = 1 ÷ 1609 mi/sec
3 ×10^8 m/sec = (3 × 10^8) ÷ (1609)
= (3 × 10^8 × 60 × 60 × 24 × 365) ÷ (1609)
= 5.88 × 10^12 mi / year
Hence, the speed of light in miles per year is 5.88 × 10^12 mi / year
