Answer 2

Answer:

Step-by-step explanation:

(a) 6³

n= 6 and  n-1 = 5

we start with 6 × 5 +1 = 31

6³= 31 + 33+ 35 + 37+ 39 + 41= 216

(b)  8³

n = 8 and n-1 = 7

we start with 8 × 7 +1 = 57

8³  = 57 + 59+ 61+ 63 + 65 + 67 + 69 + 71 =512

(c)  7³

n = 7 and n-1 = 6

we start with 7 × 6 +1 = 43

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