What is the next number in the series?
What is the next number in the series?
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.

Find the missing number in the sequence:
Find the missing number in the sequence:
In this sequence, the difference between each number is double the difference between the number that came prior to it in the sequence. For example, 
and 
. Thus, the missing number must be greater than 
by a difference of

If Angela runs 5 miles on Tuesday, 6 miles on Wednesday, and 7 miles on Thursday, how many miles will she run on Saturday if she continues with this pattern?
Angela's pattern is to run one more mile each subsequent day than the number of miles she ran the previous day. Therefore, since she ran 7 miles on Thursday, she will run 8 miles on Friday and 9 miles on Saturday. Therefore, 9 is the correct answer.
