Find the volume of a tetrahedron in the first octant bounded by the coordinate planes and the plane passing through (2,0,0), (0,1,0), and (0,0,4) using integration. use dzdydx for the order of integration. i know how to solve the problem but don't know how to find the integration limits.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
