Study the given pattern carefully and select the number that can replace the question mark (?) in it.
 First row – 13, 50, 104
 Second row – 11, 42, ?
 Third row – 18, 70, 144
 (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 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)
