*1953 = x(x + 1) /2
2* 1953 = x (x + 1)
3906 = x^2 + x
x^2 + x - 3906 = 0
(X + 63) (x - 62) =0
X + 63 = 0. ^ x - 62 = 0
X = -63 ^ x = 62
:)
I wanna say the second on but not sure
Your rate of change is 3/2.. It will always be the coefficient of 'x'
You find the squares it around, say 23, well its between 25 and 16 the pefect square roots of 5 and 4 and 23 is closer to 25 so it would be around 5
