F. An experiment because they are conducting a study and experimenting with a sample different from what is known
A1 represents the first term
d represents the common difference.....and since the common difference is 3, u have to add 3 to each term to find the next term....because with an arithmetic sequence u add to find the next term, whereas, in a geometric sequence u multiply to find the next term
5...first term
5 + 3 = 8...2nd term
8 + 3 = 11...3rd term
11 + 3 = 14...4th term
ur answer is B
First, you should multiply what's inside the parenthesis.
( 6 × 3 )x + 4 + 2x
18x + 4 + 2x
Then you add the numbers that include a variable.
18x + 4 + 2x
20x + 4
The equation can not be simplified any farther, so this is our final answer.
20x + 4
