Hillary wrote a series of numerical expressions to generate a number pattern 3+1,3+2,3+3 which table represents inputs and outputs that follow the same rule- a) input 9,10,11 output 12,13,14 b) input 9,10,11 output 13,14,15 c) input 9,10,11 output 11,12 13 d) input 9,10,11 output 27,30,33

a) input 9,10,11

output 12,13,14

Step-by-step explanation:

If we look at the pattern, number 3 is added to the consecutive input numbers 1, 2 and 3 to generate a set of output numbers.

Clearly, option (a) follows this rule. Number 3 is added to the consecutive input numbers 9, 10 and 11 to produce 12, 13 and 14.

In option (b), 4 is added to the input numbers.

In option (c), 2 is added to the input numbers and

in option (d), 3 is multiplied to the input numbers.

Hence, the correct option is (a).
