Which of the options is NOT similar to the given combination of numbers?

(8, 15, 23, 120)

Given: (8, 15, 23, 120)

Logic: 1st number + 2nd number = 3rd number, 1st number $$\times$$ 2nd number = 4th number

8 + 15 = 23, 8 $$\times$$ 15 = 120

Now, we check each options.

Option (a): (7, 14, 98, 21) (NOT Similar)

7 + 14 $$\neq$$​ 98, 7 $$\times$$​ 14 $$\neq$$ 21

​Option (b): (9, 18, 27, 162) (Similar)

​9 + 18 = 27, 9 $$\times$$​ 18 = 162

Option (c): (11, 12, 23, 132) (Similar)

11 + 12 = 23, 11 $$\times$$ 12 = 132

Option (d): (12, 5, 17, 60)) (Similar)

12 + 5 = 17, 12 $$\times$$ 5 = 60

Thus, correct option is (a).
