In the following number series, a wrong number is given. Find out that wrong number. 739 983 1541 2070 2695 3424

Let's check the pattern: 983 - 739 = 244, 1541 - 983 = 558, 2070 - 1541 = 529, 2695 - 2070 = 625, 3424 - 2695 = 729. The differences don't show a clear pattern. Try: 739 = 9^3 + 98, 983 = 10^3 - 17 (doesn't fit). Alternative: look at 1541, 2070, 2695, 3424. Differences: 529, 625, 729 which are 23^2, 25^2, 27^2. These are consecutive odd squares. Working backward: 2070 - 529 = 1541, 1541 - 441 = 1100, not 983. If pattern was 21^2 = 441, then 1541 - 441 = 1100. But we have 983, which is 1541 - 558. 558 is not a square (23.65^2). So 983 breaks the pattern.
