Given the sum 195 of 13 consecutive integers, find the sum of 4th number and 7th number of the sequence
Answer/Solution
27
Steps/Work
The median is: 195/13 = 15.
The middle position is: 13/2 = 6.5, rounded up: 7th position. So 15 is the value of the 7th position
Difference between 7th and 4th position = 3 positions less
15 - 3 = 12 = is the value of the 4th position
15 + 12 = 27 = sum of 4th and 7th number.
