Final answer:
To find the sum of positive integers divisible by 3 from 50 to 110, add up the numbers that are divisible by 3 in that range.
Step-by-step explanation:
To find the sum of positive integers divisible by 3 from 50 to 110, we need to first determine the numbers in that range that are divisible by 3. The numbers divisible by 3 in the range are: 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105, 108.
To find the sum of these numbers, add them all together: 51 + 54 + 57 + 60 + 63 + 66 + 69 + 72 + 75 + 78 + 81 + 84 + 87 + 90 + 93 + 96 + 99 + 102 + 105 + 108 = 1845.
Therefore, the sum of the positive integers divisible by 3 from 50 to 110 is 1845.
