26) Let the first number be x.

Sum of three consecutive even numbers:

Subtract 6 from both sides:

Divide both sides by 3:

To find the other two numbers, add 2 and 4 respectively:

27) Let the first number be x.

Sum of three consecutive odd integers:

Subtract 6 from both sides:

Divide both sides by 3:

To find the other two numbers, add 2 and 4 respectively:

28) Let the first number be x.

Sum of four consecutive integers:

Subtract 6 from both sides:

Divide both sides by 4:

To find the other three numbers, add 1, 2 and 3 respectively:

29) Let the first number be x.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
