The theoretical answer for the following question provided above would be found if you study
The number is increasing by 2 every time.
78 x 2 = 156
-4 + 156 = 152
The 78th term is 152
The cube root of 343 is 7.
One side has an area of 7*7 = 49 square cm
There are 6 sides to a cube
6 * 49 is the surface area = 294
