<span>This is a riddle where the answer is a student. A student usually asks a lot of questions if he/she wants to know more about a subject. Bright is here used in a pun because bright can mean both illuminated and smart. Here we are led to believe that the meaning is illuminated, but the meaning is actually smart, so students are smart and ask questions.</span>
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)
Answer:
Question 1: 0.38, 3/8, 25%
Question 2: 72oz.
Question 3: 165
Step-by-step explanation:
First Question: We can make all the numbers to decimals. 25%= 0.25, 3/8= 0.375, and 0.38 is given. Then we can clearly see that 0.38, 3/8, 25% is the order.
Second Question: There are 16oz. in a pound, so we have to multiply 4.5 and 16. 4.5*16 = 72. There are 72 oz. in 4.5lbs.
Third Question: We just have to plug 5 in, so 7(5)^2 - 10 is our equation. Following the order of equations, we have the exponent first. 5^2 is 25. We end up with 7(25) - 10. Then we have to multiply, so 7*25 = 175. Finally we have 175 - 10 which is 165.
