The explicit rule for the number of marbles in 10th row is An= 12+ n-1.
<u>Step-by-step explanation</u>:
- Total number of rows = 10 rows
- The number of marbles in the 1st row = 12 marbles
- One marble is added to each successive row
Therefore, for the remaining 9 rows out 10 rows ⇒ 9 marbles are added.
- The number of marbles in the 10th row = 12+9 = 21 marbles.
- The explicit rule is An = 12 + n-1
For n= 10, then
⇒ A10 = 12 + (10-1)
⇒ A10 =12+9 = 21
Answer:
3 - (1/5)*g
Step-by-step explanation:
One-fifth of "g" is taking the "whole" "g" and diving it by five (it could also be written as (g/5)). Subtract from 3 implies that the "3" is the starting value and and that you're subtracting one-fifth of g from that 3.
