50 of them.
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 to numbers multiply into 650?
Each of these equals 650: 1 x 650, 2 x 325, 5 x 130, 10 x 65, 13 x 50, 25 x 26
What is 50 x 50?
50 x 50 = 2500
What is x plus 50 equals 2x plus 100?
x + 50 = 2x + 100 50 = 2x+100-x 50 = x + 100 50-100=x -50=x -50+50=0 -100+100=0 it is zero
