Answer 1

Answer:

53

Step-by-step explanation:

Average of 7 numbers is 49

let a number be x

x + x + x + x + x + x + x/7 =49

7x/7 =49

7x =49 x 7

7x = 343

x =343/7

x = 49

1 is added to first number = 49 + 1 = 50

2 is added to second number = 49 + 2 = 51

3 is added to third number = 49 + 3 = 52

4 is added to fourth number = 49 + 4 =53

5 is added to fifth number = 49 + 5 = 54

6 is added to sixth number = 49 + 6 =55

7 is added to seventh number = 49 + 7 =56

Average = 50+51+52+53+54+55+56/7

= 371/7

= 53

Average is 53

Hope it helps
