Step-by-step explanation:

(a) n=6 and (n-1) = 5

∴ We start with (6 x 5) + 1 = 31

we have

63= 31 + 33 + 35 + 37 + 39 + 41=216

(c) n = 7 and (n-1) =6

∴ we start with (7 x 6) + 1 = 43

We have

73= 43+ 45+ 47 + 49 + 51 + 53 + 55 = 343

Consider the following pattern.

23-13 =1+ 2 x 1 x 3 33-23

=1+ 3 x 2 x 3 43-33 =1+ 4 x 3 x 3

Using the above pattern, find the value of the following.

(i) 73-63 (ii) 123-113 (iii)203-193 (iv) 513-503
