Answer:
A) 7 + 4(n - 1)
Step-by-step explanation:
The explicit rule follows the form, Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference between the numbers
It says that the first term is 7, so 'a' is 7. It also says that the numbers go up by 4 (adding 4 to the previous number), hence 'd' is 4.
Sub these values into the equation:
Tn = 7 + (n - 1)*(4)
Same as: 7 + 4(n - 1)
Each pink marble is 90 cents. One blue marble is a third the price of a pink marble, and since yang bought 3 times more blue marbles than pink ones, the total prices are equal. Then you account for the difference between the costs. I'm not good at explaining, hope this helped
