Answer 2

Answer:

31

Step-by-step explanation:

  Here, pattern followed :

       For three numbers a + b + c, result is given by using 2a + b + c.

 Thus, for 2 + 3 + 4 :

      ⇒ 2( 2 ) + 3 + 4

      ⇒ 4 + 3 + 4

      ⇒ 11

   For 3 + 4 + 5 :

      ⇒ 3( 2 ) + 4 + 5

      ⇒ 6 + 4 + 5

      ⇒ 15

   For 4 + 5 + 6 :

     ⇒ 4( 2 ) + 5 + 6

     ⇒ 8 + 5 + 6

     ⇒ 19

Similarly, 7 + 8 + 9 :

⇒ 7( 2 ) + 8 + 9

⇒ 14 + 8 + 9

⇒ 14 + 17

⇒ 31
