Maybe this will help: Neither spawned nor extending is the main verb of the sentence. You should not look for both of these to be in the same tense. It is best to think of these verbs as functioning to introduce modifiers, and those two modifiers should be parallel to each other. If we think of this...

When you are sure you can find the answer with both A and B, the next question you can ask yourself is if you could have figured it out with one alone. I think this helps because you don't always consider all the ways that you could find the answer with statement 1 alone and all the ways that you co...

n is greater than or equal to 2 and n is less than or equal to 15. So there are an equal number of terms in our sequence that are below the 8th term and above the eighth term: 6. Statement 2 tells us that the eighth term in the sequence is 10, so there must be 6 terms in the sequence greater than 10...

You can go around with this question for a while. The study of arithmetic is the study of number properties. So the classification could be done in using either arithmetic or number properties as the category. I would suggest you call this number properties as the OG makes number properties a subcat...

If n is odd, is x +1 odd. 1) x=n+1 2) n=13 Statement one must be sufficient. Any odd integer can be expressed as 2k+1 where k is an integer. Thus x which is equal to an odd +1 can be expressed as 2k+2. The definition of an even integer is an integer that is divisible by 2. 2k+2 must be divisible by...

Negative 1
Of course for the GMAT all primes are positive. However, negative one satisfies the Fundamental Theorem and the most common definition of a prime. Positive one is not considered prime because it is divisible be exactly one integer rather than two. Negative one on the other hand is divisible by exact...

For which of the following functions is f(a+b)=f(a)+f(b) for all positive numbers a and b? A. f(x) = x^2 B. f(x) = x+1 C. f(x) = √x D. f(x) = 2/x E. f(x) = -3x This concept seems to be tested frequently. You should recognize the pattern a(b+c) = ab + ac, which is the distributive property...

Prime factor
5^21 * 4^11 = 2 * 10^N =>
5^21 * (2^2)^11 = 2* (2*5)^N
There must be the same number of each prime on both sides of the equation. Since there are 21 fives on one side there must be 21 fives on the other.
N=21

Is there such a question that exists on the actual GMAT or in OG material? If so I would be interested in reading it. I have seen question that ask about Fermat primes, but that is not a made up concept.

I have only noticed one situation where this doesn't work and that is with a modifying phrase. For example: John bought a house, but not a very big one, with the money he saved from delivering papers. In this case the word but it used as an adverb and has a similar meaning to however. This question ...

Don't look for key words... Instead look for commas.... Adverbial phrases and contrasting conjunctions are offset by commas. To understand the flow of the passage you need to read the entire phrase that has been offset not just a key word. Plus you don't want to have to remember key words it is adde...

Here the best is answer can be identified by the use of a comma and the conjunction 'but'. Everything that follows must be a complete sentence with a subject verb and object. (At least on the GMAT this makes a complete sentence.) A) is wrong because the word 'that' subordinates the second clause. B)...
