Answer 1

Answer:

9 is the largest of All.

Step-by-step explanation:

1+2+3+4+5+6+7+8+9=45

Answer 2

Answer:

51

Step-by-step explanation:

Let the odd numbers be:  a - 6, a-4, a-2, a, a+2, a+4, a+6      ('a' is an odd no.)

Now,

Avg = (a-6 + a-4 + a-2 + a + a+2 + a+4 + a+6)/7

       = (7a)/7 = a = 45

So, the biggest odd number in the series is a+6 = 45 + 6 = 51
