The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41

1.50 = 1.50/1 = 15/10 = 3/2
1/15 because: 10+5=15 or 15/1 15/1 flipped is 1/15
10% = 1/10 15 + ((1/10)(15) = x 15 + 1.5 = x x= 16.5
The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41
20th term = 20*(20+1)/2

The question is: 2/3 - 1/5 LCM is 15. So, 2/3 becomes 10/15 and 1/5 becomes 3/15. 10/15 - 3/15 is (10-3)/15 [The whole term over 15] So, we get 7/15. The answer is 7/15.
He is 15 and its his 20th anniversary
1.50 = 1.50/1 = 15/10 = 3/2
A 20th = 1/20 = 0.05 So 0.0520 = 9.537*10-27 approx.
1/15 because: 10+5=15 or 15/1 15/1 flipped is 1/15
15 / 10 is equal to 1.5 or 1 1/2
300/15 = 20 300 is the 20th multiple of 15. So there are 20 of them between 1 and 300.
