1. Translating for loops into their underlying sequence of commands and vice versa is good practice for understanding the use of loops as shortcuts. a. The following chunk defines x to be a vector of 2 elements, then uses lines of code to define the 3rd, the 4th, the 5th, etc., out to the 500th element (most lines are omitted, but you can probably spot a pattern). Write a for loop to accomplish this feat instead. Once you have defined all elements of x with a for loop, run tail(x) to print to the screen the last 6 elements, and also print to the screen the position of the first element in x that exceeds 250. Sanity check. x[50:52] should be 37.56693 38.21966 38.87266.
