We have a4 = a1 * q^3;
Then, 16 = a1 * (1/8);
a1 = 128;
<span>The formula for the nth term of a geometric sequence is an = a1 * q^n;
an = 128 * (1/2)^n = (2^7)/(2^n) = 2^(7-n);</span>
Divide each side by 4/9 // Multiply the reciprocal, which would be 9/4
Which would leave you with
Answer:
3.5 grams of peanuts per 1 gram of raisins
Step-by-step explanation:
You have the table with the following information
14 grams of peanuts = 4 grams of raisins
21 grams of peanuts = 6 grams of raisins
35 grams of peanuts = 10 grams of raisins
you need to find:
? grams of peanuts = 1 gram of raisins
So, we need to find the constant of proportionality.
14/4 = 7/2 = 3.5/1
Therefore, 3.5 grams of peanuts = 1 gram of raisins
