What are the first five terms of the sequence defined by the given function? f(1)=-6
f(n)=f(n-1)+2, for n=2,3,4

A. -6, -8, -10, -12, -14
B. 2, 8, 14, 20, 26
C. 2, -4, -10, -16, -22
D. -6, -4, -2, 0, 2

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the discriminant is 64 + 4*1*12 = 112

this is prime.
