WebHere is how we can write an equation for an exponential function from a table of values: 1. Determine the common ratio. For example, if we see that every time x increases by 1, y is multiplied by 2, then the common ratio is 2. 2. Find the initial value of the function, or the y-intercept. This is the y-value when x=0. Webr, the common ratio, can be calculated as follows: r_n = a_n/a_n-1 (n must be greater than 1) r_n = r with a subscript of n (this is the common ratio) a_n = a with a subscript of n (this is the nth term in the sequence) a_n-1 = a with a subscript of n … WebRatio problem solving. ... The total for the ratio parts needs to be the same, so we scale up using the lowest common multiple.
