Rounded to the nearest whole number, 75.82 is 76
Check the picture below
notice, if the "r" and "h" is the same for both, the cone's volume is just 1/3 of the cylinder's
The ratio, r, is 20 - 13 = 27 - 20 = 34 - 27 = 7;
The nth term has the formula: an = a1 + (n-1) x r; where, a1 = 13 and r = 7;
Then, an = 13 + (n-1) x 7;
Finally, an = 13 + 7 x n - 7;
an = 7 x n + 6;
