Answer:
50%
Step-by-step explanation:
Because you can get either 1 and 5 which is 6 or 10 and 1 whoch is 11 but the other two will give you 15+
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
