Two groups of numbers are given below. In each set of numbers, the second number is obtained by performing certain mathematical operations on the first number ' Similarly, the second number ' is followed by certain mathematical operations to get the next number and this pattern continues in the same way. A group of verbs similar to this question follows the numbers in which of the following options? (Note - Digits cannot be separated to perform operations on two/three digit numbers, for example if number 37 is followed by number 10, then the arithmetic operation 3 + 7 cannot be performed, as two digit numbers cannot be separated into separate digits.) 5 – 12 – 26 – 47 9 – 16 – 30 – 51
