To find the number of odd integers in the sequence from 0 to 298, we need to count the number of odd numbers in that range.

The first odd number in the sequence is 1, and the last odd number is 297.

To find the number of odd numbers in that range, we can subtract the first odd number from the last odd number and divide by 2, then add 1.

(297 - 1) / 2 + 1 = 148 odd numbers.

Therefore, there are 148 odd integers in the sequence from 0 to 298.
