for the given vector [2 2 5 8], without using sum() and diff() how can i perform 2*2 + 2*5 + 5*8 = 54. Using for loop. here the consicutive number are multiplied and then addition is performed.

Ran in:
v=[2 2 5 8];
for i=1
result=v(1:end-1)*v(2:end).'
end
result = 54

I demonstrated to you in my original answer that it does give the summation. This is assuming the vector is a row vector, which it was in your original post.

total = 0;
x = [2,2,5,8];
n = length(x);
for i =1:n-1
total = total + x(i)*x(i+1);
end
disp(total)
