Direction: What value will come in place of the question mark (?) in the following question?

8, 17, 53, ?, 1079, 6479

What is the value of [ 7÷ 14 x 8 + (5 ÷ 15 x 6 - 4 × 3)]?

Study the given pattern carefully and select the number that can replace the question mark (?) in it.
 First row: 17, 26, 60
 Second row: 8, 15, 31
 Third row: 11, 19, ?
 (NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
 45 * 9 * 3 * 7 * 5 * 133
