Answer 1

Answer:

• The Missing number is 6460.

Step-by-step explanation:

Hey Mate,

Given Series is 2, 3, 8, 31, 154, 923, X

If you look carefully at this, then you will see this multiplication series.

• (i) 2 × 2 = 4 - 1 = 3
• (ii) 3 × 3 = 9 -1 = 8
• (iii) 8 × 4 = 32 -1 =31
• (iv) 31 × 5 = 155 -1 =154
• (v) 154 × 6 = 924 -1 = 923

So, Now we have to multiply with 7 and subtract 1..

• (vi) 923 × 7 = 6461 -1 = 6460

So, The Missing number is 6460.
