What is the equation for a geometric sequence with a first term of 4 and a second term of −12? an = 4(−3)n − 1 an = 4(3)n − 1 an = 4(36)n − 1 an = 4(−36)n − 1

Option 1  :

Step-by-step explanation:

The geometric sequences have the following form:

Where is the first term in the sequence

We know that the first term is 4

Then = 4

We also know that the second term is -12

Then

We know that in geometric sequences the relationship between consecutive terms is constant. So:

r = -12/4

r = -3

Finally the general formula of this sequence is:

  Option 1

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
