Question

Find out the missing number/words.

13 (168) 13, 14 (181) 13, 15 (?) 13

Options

• 196

• 195

• 190

• 194

Answer 1

194

Explanation:

The pattern is as follows:

13(168) 13 ⇒ 13 × 13 = 169 - 1 = 168 (Middle number)

14(181) 13 ⇒ 14 × 13 = 182 - 1 = 181 (Middle number)

and 15 (?) = 13 ⇒ 15 × 13 = 195 - 1 = 194 (Middle number)
