Answer»

As per given data,

AVERAGE of 7 CONSECUTIVE numbers = 41

Total summation of 7 numbers = 41 × 7

Total sum of 7 numbers = 287- - - - (1)

Let the initial number be x

Consecutive numbers series will be - x, x + 1, x + 2, x + 3, x + 4, x + 5, x + 6

From result (1) -

Total sum of 7 numbers = 287

⇒ x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) = 287

⇒ 7x + 21 = 287

⇒ 7x = 266

⇒ x = 38

⇒ Last number = x + 6 = 38 + 6 = 44
