Distance traveled from well to first tree then back to well for watering first tree = 10+10 m = 20 m
distance between trees = 5 m
Distance traveled from well to second tree then back to well for watering second tree = 15+15 m = 30 m
Distance traveled from well to third tree then back to well for watering third tree = 20+ 20 m = 40 m
Hence , total distance D travelled to water 25 trees is given by sum of following series
D = 20 m + 30 m + 40 m + ...............................................
Above series is in arithmetic progression that has 25 terms . First term a = 20 and the common difference d = 10 .
Sum of 25 terms is calculated using the formula "
" , where n = 25 is number of terms
