Look at this series: 34, 56, 80, 106 ....... What number should come next?

This series is an increasing series. Each number in the series is 22 more than the previous number plus an increment of 2.

Here's how it works:

• The difference between 56 and 34 is 22.
• The difference between 80 and 56 is 24.
• The difference between 106 and 80 is 26.

So, the difference between the numbers is increasing by 2 each time.

Therefore, the difference between the next number and 106 should be 28 (26 + 2).

So, the next number in the series should be 106 + 28 = 134.
