If the sum of first 75 terms of an A.P. is 2625, then the \( 38^{th} \) term of the A.P. is:

If \( -5, k, -1 \) are in A.P., then the value of \( k \) is equal to:

Let \( x_1, x_2, \dots, x_n \) be in an A.P. If \( x_1 + x_4 + x_9 + x_{11} + x_{20} + x_{22} + x_{27} + x_{30} = 272 \), then \( x_1 + x_2 + x_3 + \dots + x_{30} \) is equal to:
