Question

For a certain function $u_x$ , given that $u_0 = 3, u_1 = 12, u_2 = 81, u_3 = 200, u_4 = 100, u_5 = 8$ , then $\Delta ^{5}u_{x}$ is equal to

• A. $750$
• B. $778$
• C. $765$
• D. $755$

Answer 1

Answer: (D)

$755$

Answer 2

Given, $u_{0}=3, u_{1}=12, u_{2}=81, u_{3}=200$ $u_{4}=100, u_{5}=8$ Then, Hence, $\Delta^5u_x = 755$
