For me, it is equal to the square of the first terms minus the square of the second terms...:-)
For example . . .
(9x + 5) (9x - 5)
= (9x)2 - (5)2
= 81x2 - 25
The former answer was this:
"it is equal to the square of the first term minus the square of the second term"
If we answer in that way, the solution is this:
(9x + 5) - (9x -5)
= (9x + 5)2 - (9x - 5)2
= (81x2 + 25) - (81x2 + 25)
= 81x2 + 25 - 81X2 - 25
= 0
Let us use the DCMC or Dalope's Coefficient Method of Checking: (Checking the answer using only the coefficients)
= (9 + 5) - (9 - 5)
= (14) - (4)
= 10
Our answer to the problem (9x + 5) (9x - 5) using the "it is equal to the square of the first term minus the square of the second term" is 0 but the DCMC answer is 10. There is conflict with the answer!
But if we answer in this way: "it is equal to the square of the first terms minus the square of the second terms" the answer would be 81x2 - 25 and it's answer in DCMC is 56. Let me prove it:
(9 + 5) (9 - 5) (9 + 5) ( 9 - 5)
= (14) (4) or = 81(9 x 9) - 25(5 x -5)
= 56 = 56
Conclusion: The only mistake in the former answer (it is equal to the square of the first term minus the square of the second term) is HIS SOLUTION TO HIS GIVEN EXAMPLE IS CORRECT BUT HIS ANSWER TO THE QUESTION "The product of the sum and difference of the same two terms is equal to what?" IS WRONG OR HE MISSED ONLY TO MAKE THE WORD "TERM" PLURAL!
:-) I hope that my answer will correct your understanding about the above question guys!!!

They are multiples of the same number.
The definition is, as given in the question, a sequence where the difference between any pair of consecutive terms is the same,.
Lowest terms and simplest terms are the same. "Simplest form" is used more often.
they are equal
Yes, they are the same. The trailing zero makes no difference.
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
In math terms difference means to subtract. :)not the same not the same
They are multiples of the same number.
The two ratios are said to be equal when even if we multiply both terms by the same number or divided both terms , the equivalent fraction or simplest fraction is the same.

Being the same refers to having identical characteristics, qualities, or components. Being equal refers to having the same value, amount, status, or importance. In other words, things that are the same are identical, while things that are equal may be different but still have an equivalent value.

they are equal
There is no difference between "glow sticks" and "glowsticks." Both terms refer to the same product, which is a plastic tube containing chemicals that produce light when mixed together.
yes...to know if it is equal use cross multiplication..if the answer is the same as the product of the denominetor to the numerator,it is equal
I dont know the actual answer, but what is the point in Cc if it the same as ml? I mean like, why would somebody make something that is named different, but excactly the same as a better known product, measurement, etc.
