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.
What do you call the parallel lines that cicle the globe?
The ones going from north to south are LONGITUED the ones from east to west are LATITUDE
What horizontal lines?
Those ones!

What is the one's digit of 7 to the 2015th power Explain the steps you took to reach your answer.?
It is a 3. Look at the ones digit of successive powers of 7; this need only be done by considering the multiplication of the ones digit of the previous power of 7 by 7 (as this is the only calculation that affects the ones digit as each successive power of 7 is the previous power multiplied by 7) and taking the result modulus 10 (to extract the new ones digit as any excess over 9 is carried into the tens column): 7¹ → 7 mod 10 = 7 7² → (7×7) mod 10 = 9 7³ → (9×7) mod 10 = 3 7⁴ → (3×7) mod 10 = 1 7⁵ → (1×7) mod 10 = 7 At this point the pattern of the ones digit will obviously repeat the sequence of the four digits {7, 9, 3, 1}. To find the ones digit of any power of 7, take that power modulus 4 use that digit from the four digit sequence. Note that when taking the number modulus 4, the result will be in the range 0-3; when the result is 0, use the 4th digit from the sequence. 2015 mod 4 = 3 → the third digit of {7, 9, 3, 1}, which is 3, will be the ones digit of 7²⁰¹⁵.
What numbers do you find in the ones digit of 5?
5 and 0
What numbers do you find in the ones digit for the number2?
Okey-dokey. I have no idea what the heck you are asking. 'What numbers do you find in the ones digit for the number 2?' Well, the number 2 is only one digit, so the answer would be, '2.' DUH!
If you compute 7 to the 100 power what digit will be in the ones place?
Seven to the 100 power equals 700. In the ones place there would be the number zero.
2.14 were is the ones digit?
The 2 is the ones digit. ■
How many two digit numbers are there in which the tens digit is greater then the ones digit?
The answer depends on what the tens digit is greater than, and what the ones digit does then.

91
