Answer:
common difference=5
number of term(n)=20
Step-by-step explanation:
a=4,
but T_{4} =19= a+3d
a+3d=19
4+3d=19
3d=19-4
3d=15
d=15/3
d=5
=a+(n-1)d
99=a+(n-1)d
99=4+(n-1)*5
99=4+5n-5
99=5n-1
5n-1=99
5n=99+1
5n=100
n=100/5
n=20
Answer:
Choice C.
Step-by-step explanation:
For an expression to be equivalent you need to multiply or divide the 2 numbers in the original expression by the same number.

The odd one out is C because 125.78 has been divided by 100 but 1.23 has been multiplied by 10.
