Question:
What are the next 2 numbers in the pattern? 2, 7, -1, 10, -4, 13, _, _
Answer:
The next two number are -7 and 16
The pattern is : To get odd position number, subtract 3 from the previous odd position number. Similarly, to get even position number, add 3 to the previous even position number.
The odd position numbers are : 2, -1, -4
The next odd position numbers are : -7, -10, -13 and so on.
The even position numbers are : 7, 10, 13
The next even position numbers are : 16, 19, 22 and so on.
Hence the series is 2, 7, -1, 10, -4, 13, -7, 16, -10, 19 ....
