Step-by-step explanation:
He earned $20 because 20% of $100 is $20
It is 2.4 because 16 goes twice and the remainder is 4
Step-by-step explanation:
The first term of the AP (a) = 3
and common difference (d) = 8-3= 5
therefore, a+(n-1)d = 78
=> 3+(n-1)5= 78
=> n-1=75/5
=> n-1 = 15
=> n= 16
16th term of the AP is 78
