Question

Quizplus · Accepted Answer

To insert four arithmetic means between 18 and 43, we find the common difference by dividing the difference between 43 and 18 by the total number of intervals (5 in this case, since we're adding four means plus the original interval). The difference is 43 - 18 = 25, and 25 / 5 = 5. Therefore, each number increases by 5, starting from 18: 18, 23, 28, 33, 38, 43.
