    Sequences and Series Question (Grade 11)

    Determine the value of n for which (2^1)(2^2)(2^3)(2^4)...(2^n) = (2^253) Here's my work so far: 2^1 x 2^2 x 2^3 x 2^4... 2^n = 2^1+2+3+4+...+n, where 1+2+3+..., tn = 253 2^2.2^3 = 2^2+3 = 2^5 = 32 I'm confused on what to do next?

    Fibonacci Seq bit string proof. Show that pattern can't have three consecutive 1s

    I'm having a little trouble figuring out how to prove this. So, the sequence is as follows: S0 = 0 S1 = 1 S(n-2)S(n-1) for all n >= 2 That means S2 = 10 S3 = 101 S4 = 10110 S5 = 10110101 Now the question that I'm stuck on is: Prove that the pattern can't have three consecutive ones...

    Is there a certain pattern for Kleene closure of a language?

    Hi guys. I'm currently studying formal languages for our class. I encountered this example on our study material which I'm not fully understanding: Alphabet = {0,1} K1 = {10,1} K2 = {011,11} K1* = {e, 10, 1, 101, 11, 101010, 10101, 111, 11110, ...} K2* = {e, 011, 11, 011011, 01111, 1111...

    Pattern or Delusion

    We go from natural numbers to integers and gain closure for the operation of subtraction while losing the notion of beginning. We go from integers to rational numbers and gain closure for the operation of division while losing the notion of next. We go from reals to complex numbers and gain...

    Diminished Radix Complement (geometric pattern)

    So I'm reading about Radix Complements on Wikipedia, and there is a geometric pattern used to prove the following statement: The radix complement is most easily obtained by adding 1 to the diminished radix complement, which is (bn-1)-y. Since bn-1 is the digit b-1 repeated n times because bn-1...

    How can I find the pattern ?

    If we assumed 13 = 24.14445188 16 = 133.0360355 18 = 460.2708264 22 = 6793.53781 36 = 441887042.5 Then find 25=??

    primes squared inf showing a pattern with the last digits

    1. so if i take a prime and square, cube, etc inf times, the last numbers will (so far) be four numbers repeating inf. 2. if i take 5 to the 3rd power and up inf times the last 3 numbers will alternate between 125 and 625. My background in this is type of working numbers is non existent. Up...

    Line Integral for a sawtooth pattern

    I have to evaluate the line integral: \int_Z(sin y + 2x) dx + (2y + x cos y)dy from the point (0,0) to (1,1) to (3,-1) to (4,0). I evaluated the integrals for each of the 3 separate lines such that: \int_Z = \int_{C_1} + \int_{C_2} + \int_{C_3} I got the answer of 2cos(1) - 3sin(1) -7 but I...
