Answer:
<em>4 is the unit's digit of the 20th number.</em>
Step-by-step explanation:
Let us try to find out a pattern for the unit's digit of the terms.
1st term is 1, so unit's digit of 1st term is 1.
2nd term 
so unit's digit is 4.
3rd term 
so unit's digit is 9.
4th term 
so unit's digit is 4.
5th term's unit digit: Square of unit's digit of 4th term + 3
i.e. 9.
:
We can see that the pattern is
3rd, 5th, 7th ...... terms have 9 as the unit's digit.
2nd, 4th, 6th.... terms have 4 as the unit's digit.
So, 20th term will have 4 as the unit's digit.

1:</h2>
- A mile unit is equal to 1760 yards. inches =mile * 63360 2*63360=126720
2 Miles = 126720 Inches
- There are 36 inches in a yard
3600/36= 100
3600 inches = 100 yards
6800/1000 = 6.8
6800 m = 6.8 km
15000/100=150
15000 cm=150 m
2:
a) Johnson ran yard in second= 9
1 minute = 60 second
Johnson ran yard in one minute= 9 *60= 540 yards
b) Johnson ran yard in second= 9
1 hour = 60 minutes *60 second= 1200 seconds
Johnson ran yard in one hour= 9 *1200= 10,800 yards
c) Johnson ran yard in one hour= 9 *1200= 10,800 yards
1 mile = 1760 yards
miles did he run in one hour= 10,800 / 1760 =6
Johnson ran 6 mile in one hour
