Consider the following statements for the sequence of numbers given below : 11, 111, 1111, 11111, ..... 1. Each number can be expressed in the form (4m + 3), where m is a natural number. 2. Some numbers are squares. Which of the above statements is/are correct ?

Answer: Option A

11, 111, 1111, 11111,.....
Let m = 2 ⇒ 4 × 2 + 3 = 11
m = 27 ⇒ 4 × 27 + 3 = 111
Each number can be expressed in the form (4m + 3) where m is a natural number.
Hence, statement 1 is only correct.
