                  Let us see one more pattern as given below.

                  In this pattern, vertical and horizontal arrows come alternately by changing their

                  directions and one arrow is added at each step. This is an example of analogical

                  pattern.

                  Pattern in numbers

                  Look at the patterns in the numbers given below.

                  1.  2 4 6 8 10 12 ...

                       2 is added every time to find the next number in the pattern.

                  2.  5 9 13 17 21 25 29 ...

                       Each next number is obtained by adding 4 to the previous number.

                  3.  100 90 80 70 60 50 ...

                       10 is subtracted every time to find the next number in the pattern.

                  Pattern in Letters

                  Observe the pattern in the following sequence of letters.

                  A C E G I K ...
