What is 20 decreased by 8?
The difference between 72 and 16
What is the nth term for 22 14 6 -2 -10?
To find out the equation for a sequence, the first thing you note is the difference between the numbers. In this case the difference is: -8, -8, -8, -8 Thus the formula will be x-8n where x is not yet known. For linear sequences like the one above, x is the 0th term. In this case it would be the term that would come before 22, or 22+8, or 30. Thus the equation for the nth term is 30-8n
What are two numbers whose sum is 52 and difference is 8?
Let this numbers be x and y, then x + y = 52 x - y = 8 x = 8 + y x + y = 52 substitute 8 + y for x into the first equation; 8 + y + y = 52 8 + 2y = 52 subtract 8 to both sides; 2y = 44 divide by 2 to both sides; y = 22 x = 8 + y substitute 22 for y into the equation; x = 8 + 22 x = 30 Thus this numbers are 22 and 30. 22 & 30
