Fig Working Unit cubes
1 2(1) -1 = 2-1= 1
2 2(2)-1 = 4-1= 3
etc….
(a) 5 2(5)-1 = 10-1= 9
(b) 19 2(19)-1=38-1= 37
(c) nth term = 2n-1
2n-1 = 169
2n = 170
n = 85 means Figure 85 has 169 unit cubes.
Yes, good equation of 2n -1.
I’ve thought of another equation 2(n-1) + 1. Works to be the same as 2n -1 lol.
