Ans: 1 Reason is that the last digit forms a repeated pattern. For 3^n, last digits are 3, 9, 7, 1 for n = 1,2,3,4. First repeated sequence goes from n= 1 to 4 Second repeated sequence goes from n= 5 to 12 50 th repeated sequence is 197, 198, 199, 200 To generalize this problem further: n th repeated sequence of "x" numbers goes from n*x-3, n*x-2, n*x-1, n*x See discussion page for additional thoughts.

What three digit number has a horizontal line of symmetry?
It can be 111 or 333, depending on how you write your ones and your threes. * * * * * 0 and 8 also have horizontal symmetry so any number made up from 0, 1, 3, 8 will do. For example, 108.
Is there a formula for calculating the value of pi?
Yes. There are several, but some are "hard to use" or "hard to understand" and some other ones, particularly the "simple and easy" ones take a lot of work (a lot of steps) to derive "the next digit" in the sequence. Use the link to the Wikipedia article on calculating the value of pi and see what you think will work for you. If push comes to shove, there is software that will turn your PC into a pi computing machine. Need a link to the Wikipedia article? You got it.
Does a trapezoid have four sides of equal length?
no it does not have equal sides. two lines on top are equal, but not with the ones on the side. the ones on the side are equal as well.just not with the ones on the top.
