Aman launches his boat from point a on the back of a straight river, 3km wide, and wants to reach point b, 8km downstream on the opposite bank, as quickly as possible. he could row his boat directly across the river and then run to b, or he could row to some other point across the river and then run to b. if he can row 6km/hr and run 8km/hr, where should he land to reach b as soon as possible?

answer: i don't understand it

step-by-step explanation: sorry

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
