How to display the first ten series: 1,--3,5,-7,9,.............

The first term of the series must be positive and then negative and then positive and then so on.

Like this? for (int i = 1, count = 0; count < 10; i+=2) { System.out.print((count % 2 == 0 ? "" : "-") + i + " "); count++; }

Hint: The nth element of the series is equal to a_{n-1}+4*n*(-1)^n
