Which expression represents the series 1+5+25+125+625
solong [7]
So if you want to find the nth term so
1st term=1
2nd term=5
3rd term=25
we notice that 5^1=5 and 5^2=25 , but they are on the second ones so
the expression is

the nth term=5^(n-1)
so 1st term=5^(1-1)=5^0=1
2nd term=5^(2-1)=5^1=5
3rd term=5^(3-1)=5^2=25
and so on


the expression is 5^(n-1)

Group C ran more miles an individual.

Explanation: To find the number of miles per individual, you must subtract the total number of miles by the total number of people who ran those miles. Which ever answer is larger, tells us which group ran more miles an individual.

Here are the calculations-

Group C: 27/4=6.75
Group D: 39/6=6.5

As you can see, Group C ran more miles an individual than Group D.

What problem is Chen checking 152x4=608+2=610
tester [92]
The +2 is a reminder to add when he multiply 4*1 (4*1=4+2=6)
4*2=8
4*5=20 (so he writes the 0 with a remainder of 2)
4*1=4+2=6
so,
152x4= 608
