John increased the amount of water he drinks everyday from 20 fl oz to 48 fl oz. By what percent did John increased the water he drinks?

140%

Step-by-step explanation:

Percentage change in any variable is given by

percentage change = (new value - old value)/ old value * 100

Given

Earlier amount of drinking water = 20 fl oz

New amount of drinking water = 48 fl oz

Percentage increase in drinking of water = (48-20)/20 * 100 = 28/20 * 100

Percentage increase in drinking of water =  28*5 = 140 %

Thus, there is 140% percentage increase in water by John.

3 is greater then both of those numbers

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
