To solve the problem, we need to find the arithmetic progression (A.P.) given the conditions about the sums of certain terms. Let's denote the first term of the A.P. as \( A \) and the common difference as \( D \). ### Step 1: Write the expressions for the terms The \( n \)-th term of an A.P. is given by the formula: \[ T_n = A + (n - 1)D \] Thus, we can express the 4th, 6th, 8th, and 10th terms as follows: ...
