What is the next number in the series: 98, 110, 122, 134, 146, _?

To determine the next number in the series, it's essential to analyze the pattern of differences between the consecutive numbers. Starting from the beginning:

• The difference between 98 and 110 is 12.

• The difference between 110 and 122 is also 12.

• The difference between 122 and 134 remains 12.

• Finally, the difference between 134 and 146 is again 12.

From this observation, it's clear that the series increases consistently by 12 with each subsequent number. Continuing that pattern, if we take the last number, which is 146, and add 12, we arrive at:

146 + 12 = 158.

Thus, the next number in the series is 158. This consistent addition signifies a predictable arithmetic sequence, which is why identifying that pattern is crucial when determining future numbers in such sequences.
