D. 62(11^62)
E. 63(11^63)

Or, $$\frac{(11^{61} + 11^{63})}{2}$$

Or, $$\frac{11^{61} ( 1 + 11^2 )}{2}$$

Or, $$\frac{11^{61} *122}{2}$$

Or, $$61*11^{61}$$

Thus, answer must be (C) $$61*11^{61}$$

The average of two numbers is their sum divided by 2:

Avg = (11^61 + 11^63)/2

From the numerator, we can factor out 11^61 from each term:

Avg = [11^61(1 + 11^2)]/2

Avg = [11^61(122)]/2

Avg = (11^61)(61)
