Irrespectiveof the fact that "beside" is more formal and "next to" is a bit more casual, I was wondering whether I have been wrong in defining the following pairs as correct or incorrect: 1.a. Come and sit beside me. (Correct) 1.b. Come and sit next to me.(Incorrect--- doesn't sound idiomatic to me) 1.c. Come and sit by me. 55 , 9 9 , 13 13 , 17 17 , 21 21. This is an arithmetic sequence since there is a common difference between each term. In this case, adding 4 4 to the previous term in the sequence gives the next term. In other words, an = a1 +d(n−1) a n = a 1 + d ( n - 1). Arithmetic Sequence: d = 4 d = 4. This is the formula of an arithmetic sequence. Forexample, if your'e out in public and see someone who is about 5'9-5'11, would you perceive them as your height or taller? Can you tell 2-5" difference? Because I find that when I see someone 5'9-6'0 I see them as taller unless I actually stand next to them.

And no matter how far you keep going, you will always land on a perfect square. Plus, if you look closer, you might notice another pattern. The sum of the first three odd numbers = 9 = 3², add the next one to get 4², and so on. This is why x² + 2x + 1 always lands on a . 89 38 91 421 470 44 284 430
