Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First term [ a ] = 6.3
Common difference [ d ] = 8.8 - 6.3 = 2.5
Using general term formula,

78.8 = 6.3 + (n-1)*2.5
2.5*(n-1) = 72.5 [ Dividing both sides by 2.5 ]
n-1 = 29
n = 30
Hence, 78.8 is the
30th term in the arithmetic series.

given
=
( cross- multiply )
10j = 54 ( divide both sides by 10 )
j =
=
← in simplest form

let h be the hours worked daily , then
3h = 20
=
( divide both sides by 3 )
h =
÷ 3
