What are arithmetic sequences

1 answer:

7 0

In an arithmetic sequence, the difference between consecutive terms is always the same. For example, the sequence 3, 5, 7, 9 ... is arithmetic because the difference between consecutive terms is always two.

Part A:

Variable is a symbol for a number we don't know yet. It is usually a letter like x or y but can be any letter.
Example: 6z means 6 times z, and "z" is the variable.

Hence, the variables are c and w. [ Choose any one for your answer ]

Coefficient is any number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Hence, the coefficients are 20 and 5. [Choose any one for your answer]

A constant is a fixed value which does not change regardless of the variables entered.

Hence, the constant is 95.50

Part B:

Weeks saved (w) = 20

Cars washed (c) = 5

20c + 5w + 95.50 = (20 * 5) + (5 * 20) + 95.50 = 100 + 100 + 95.50 = 295.50

Hence, Marla will have $ 295.50 in her account.

Part C:

In 20c + 5w + 95.50, Marla's mom deposits $ 20 after every car wash.

If Marla's mom deposits only $ 10 after every car wash, then, the new equation would be : 10c + 5w + 95.50

Hence, the coefficient will change from 20 to 10.
