First, determine what the pattern is in the series. The pattern here is to multiply the previous number by 2 and then add 1. Therefore, multiply 47 by 2 (which is 94), and then add 1. The result is 95.

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of Thus,

In this sequence of numbers, there is an important pattern to recognize. In this sequence each number is a prime number, however the sequence skips every other prime number. Thus, the sequence begins with the prime number and then skips the prime number (which is the only even prime number) and goes to . From the next prime number is , however since the pattern in this sequence skips every other prime number--the missing number is .

The numbers increase by 5. Given that the number before n is 20, the value of n is .

In this sequence, every subsequent number is less than the preceding number. Given that the number that precedes is , the value of w is . Therefore, is the correct answer.

In this sequence of numbers, there is an important pattern to recognize. Each number is less than the previous number by a difference that is double the margin between the previous two numbers. For example, the difference between and is And, the difference between and is . Thus, the missing number must be less than by a difference of --which means that is the missing number.

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by double the difference between the two previous numbers. is greater than by a difference of , therefore the number that is missing must be greater than by a margin of . Thus, the correct answer is . Notice that is also less than by a difference of

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of . Therefore, the missing number is , because

In this sequence of numbers, there is an important pattern to recognize. Each number in this sequence is a composite number--however, the sequence skips every other composite number. Thus, the next composite number after is --which is skipped because of the pattern, making the correct answer .

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of . Thus, the correct answer is , because
