What is the next number in the sequence 1, -1, 2, -2, 3
mylen [45]

Answer:

-3

Step-by-step explanation:

There are two ways to see what the next sequence number would be in this case.

First approach, you start with the first number (1) than count every other number, which are all positive integers.  You do the same starting from the second number (-1), which would then be all negative integers.

Second approach, consider 2 consecutive numbers being a single element of the series... each has a number (1,2,3) with its positive and negative values.

Select the option fo “?” That continues the pattern in each question. <br> 3, -6, 12, 4, 20, ?
Elza [17]

Answer:

The sixth number in series is 13.

Step-by-step explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12  - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) =  13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.
