Given parameters:
First term of the sequence = x
Second term = x + 2
Third term = x + 4
Sum of the first three terms = 72
Unknown:
First term of the sequence = ?
Solution:
The sum of the first three terms is unknown;
(x) + (x + 2) + (x + 4) = 72
Solve for x;
x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6
3x = 66
x = 
= 22
The first term of the sequence is 22
The answer to this equation would be 10!
Steps:
Add 3 to both sides of the equation this would add 3 to 37 making it 40 and when you add 3 to -3 it cancel out so the new equation should look like this!
4x=40
The next step is to divide both sides by four and you get the answer!
X=10
