What number is next in this series 2-10-26-50-82?
Given the sequence 2, 10, 26, 50, 82, ... We can look at the differences between these numbers: 2 + 8 = 10 10 + 16 = 26 23 + 24 = 50 50 + 32 = 82 and can see that this sequence increments by a value which starts at 2, and itself increments by eight. This means we can describe this sequence with this function: x f(x) = 2 + 8∑x 0 f(x) = 2 + 8( x(x + 1) / 2) f(x) = 2 + 4(x2 + x) f(x) = 4x2 + 4x + 2 f(x) = 2(2x2 + 2x + 1) The next value in the sequence then would be: f(5) = 2(2 * 52 + 2 * 5 + 1) = 2(50 + 10 + 1) = 2 * 61 = 122
What is the answer to this sequence 20 10 100 50 500?
The sequence appears to be alternating between dividing by 2 and multiplying by 10. Starting with 20, we divide by 2 to get 10, then multiply by 10 to get 100, then divide by 2 to get 50, and finally multiply by 10 to get 500. Therefore, the next number in the sequence would be 500 divided by 2, which equals 250.
What is 10 divided by 20 over 50?
10 divided by 20/50 = 25= 10÷ 20/50= 10/1÷ 2/5= 10/1 * 5/2= 50/2= 25
What is the sequence of 100 52 28 16 10?
The sequence is formed by dividing the previous number by 2 then adding 2. 100/2 = 50, 50 + 2 = 52 52/2 = 26, 26 + 2 = 28 28/2 = 14, 14 + 2 = 16 16/2 = 8, 8 + 2 = 10 The next number in the sequence is thus :- 10/2 = 5, 5 + 2 = 7
How many ways can you divide 50?
Assume that the answer is a positive integer. Convert 50 into its factor pairs. 1 x 50 2 x 25 5 x 10 As all of the above numbers divide 50 then there are 6 ways. 50 ÷ 1 = 50 : 50 ÷ 2 = 25 : 50 ÷ 5 = 10 : 50 ÷ 10 = 5 : 50 ÷ 25 = 2 : 50 ÷ 50 = 1
