Complete the recursive formula of the geometric sequence 7, -14, 28, -56,

= - 2

Step-by-step explanation:

A geometric recursive formula has the form

= r

where r is the common ratio

Here r = - 14 ÷ 7 = - 2, thus

= - 2 with a₁ = 7

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
