prove that for x is an odd, positive integer, 3x ≡−1 (mod 4). I'm not sure how to approach the problem. I thought to assume that x=2a+1 and then show that 3^x +1 is divisible by 4 and thus congruent to 3x=-1(mod4) but I'm stuck.

The Fibonacci numbers are recursively dened by F1 = 1; F2 = 1 and for n > 1; F_(n+1) = F_n + F_(n-1): So the rst few Fibonacci Numbers are: 1; 1; 2; 3; 5; 8; 13; 21; 34; 55; 89; 144; : : : There are numerous properties of the Fibonacci numbers.
a) Use the principle of Strong Induction to show that all integers n > 1 and m > 0
F_(n-1)F_(m )+ F_(n)F_(m+1) = F_(n+m):
Solution. (Hint: Use induction with respect to m. First verify the formula the base case,for m = 1 case (here use again induction on n) the assume that it is true for m = 1;m = 2; ;m = k then prove that it remains true if m = k + 1 (still with the use of induction on n)

Provide an example:
1) A sequence with infinitely many terms equal to 1 and infinitely many terms that are not equal to 1 that is convergent.
2) A sequence that converges to 1 and has exactly one term equal to 1.
3) A sequence that converges to 1, but all of its terms are irrational numbers.

Diane has decided to play the following game of chance. She places a $1 bet on each repeated play of the game in which the probability of her winning $1 is .6. She has further decided to continue playing the game until she has either accumulated a total of $3 or has lost all her money. What is the probability that Diane will eventually leave the game a winner if she started with a capital of $1? Of $2?

Here are five different functional models that might represent the growth of the number of Zika cases, where x represents the week number, and y represents the number of cumulative cases.
1. Linear y = 258.74x
2. Logarithmic y=937.37ln(x)-202.03
3. Quadratic y = 31.357x ^(2 )+ 134.93x − 122
4. Power y = 55.278x ^2.0101
5. Exponential y=47.399e^(0.6737x)
For each function model listed, create a graph for 1 ≤ x ≤ 5, along with the Zika case data from Step 2. Be sure your graphs clearly label the function and the actual data.
Step 2 that the question is referring to is
Below is data of the weekly number of suspected Zika cases in French Polynesia in 2013.Plot the data on the graph below.
