Answers True or False

  1. True.  Alpacas are members of the camelid family.  This includes South American llamas, guanacos and vicunas as well as the African and Asian Bactrian and dromedary camels.   All of these animals originated in the plains of North America around 10 million years ago.  So camels are native to North America!

Tricky Questions

  1. $6.20 ( one dollar per consonant and five cents per vowel)
  2. If one of the coins if not a nickel, then the other one is.  The Brother has a dime and a nickel.
  3. Once, because 25-1 = 24.  IF you subtract one again, it would be from 24.
  4. 44. Starting with 4, every number is the sum of the previous three.
  5. 49.  Each number is a square of the numbers I the. Sequence.  1= 1squared, 4 = 2 squared, 9 = 3 squared and so on’
  6. 354.  The sequence consists of a number followed by its palindrome, or dunber with the digits in reverse
  7. 132 seconds.  We know that at 8 o’clock the clock makes eight strikes, taking seven seconds. Each interval between the strikes is one second long.  This pattern applies to every hour on the hour.  For example, at nine o’clock, the clock will make nine strikes, separated by eight intervals, lasting one second each, so it will take the clock 8 seconds to s trike nine o’clock. In general, at each hour the clock will need one second less than the number of the hour to strike that hour.  The one exception is one o’clock when the strike coincides with the hour and thus requires zero seconds. Whew!
