What is the next number in the series?83 121 159 197 235 __?__

The given series is: 83, 121, 159, 197, 235

To find the next number in the series, we need to identify the pattern.

Let's subtract the first number from the second:

121 - 83 = 38

Then, subtract the second number from the third:

159 - 121 = 38

And the third number from the fourth:

197 - 159 = 38

And the fourth number from the fifth:

235 - 197 = 38

So, the pattern is that each number in the series is 38 more than the previous number.

To find the next number, we add 38 to the last given number:

235 + 38 = 273

So, the next number in the series is 273.
