2. 7
3. 9
4. 8​

Answer 1

Answer:

9

Step-by-step explanation:

Five consecutive numbers are:-

x, x + 1, x + 2, x + 3, x + 4

Mean = 7

= x + x + 1 + x + 2 + x + 3 + x + 4 ÷ 5 = 7

= 5x + 10/5 = 7

= 5x + 10 = 35

= 5x = 25

= x = 5

Consecutive numbers are:- 5, 6, 7, 8 and 9.

Largest number is 9.
