(n-1)-3 = (3n)/2 This is the equation used to represent the information given
For the sequence 2, 6, 18, 54, ..., the explicit formula is: an = a1 ! rn"1 = 2 ! 3n"1 , and the recursive formula is: a1 = 2, an+1 = an ! 3 . In each case, successively replacing n by 1, 2, 3, ... will yield the terms of the sequence. See the examples below.
Answer:
4
Step-by-step explanation:
For this case we have a function of the form
, where
. We must find the values of "and" according to the following function:
So:

Thus, the values are:
24,8, -12
Answer:
24,8, -12
11^2=121
12^2=144
You can write either 11 or 12.
