  • The man walks 2 kilometers on the first day, and then each subsequent day he walks half the distance of the previous day. This forms a geometric progression with the first term (a) as 2 and a common ratio (r) of 1/2.br /The formula to find the sum of a geometric progression (S) is given by:br /S = a / (1 - r)br /In this case, a = 2 and r = 1/2. Let's calculate the maximum total distance walked in his lifetime:br /S = 2 / (1 - 1/2)br /S = 2 / (1/2)br /S = 2 * 2br /S = 4 kilometers

  • 4km it is actually a geometric infinitive progression where the ratio is 0.5 and the first term is 2km. equation for infintive gp S= A/(1-r)

  • its a GP. solve by Sn formula. a/(1-r) here a is 2 and r is 1/2.
