Answer:85.15
Step-by-step explanation:
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;
8 x 3 is 24
3 x 8 is 24
6 x 4 is 24
24 x 1 = 24
Hope that helped you and I didn't know when you meaned by 2 facts and 1 fact
