For each of the following sequences find a functionansuch that the sequence is a1, a2, a3, . . ..

You're looking for a closed form - in particular, your answer may NOT be a recurrence (it may not involveany otherai). Also, while in general it is acceptable to use a "by cases"/piecewise definition, for this task you must instead present a SINGLE function that works for all cases.(Hint: you may find it helpful to first look at the sequence of differences of consecutive terms.)

1) 7,1/11, 15,1/19, 23,1/27, 31,. . .

2) 1, 2, 2, 3, 3, 3, 4, 4, 4, 4,. . .where each i∈N is repeated i times. (Hint: one or more of the following may be useful: floor function, Gauss sum, quadratic formula)

We say that an infinite sequence a0,a1,a2,a3,… of real numbers has the limit L if for every strictly positive number ε, there is a natural number n such that all the elements an,an+1,an+2,… are within distance ε of the value L. In this case, we write lim a = L. Express the condition that lim a = L as a formula of predicate logic. Your formula may use typical mathematical functions like + and absolute value and mathematical relations like...
