If m 4 = 75 then what is m 8
105
75
175
25
To find the value of m8, we first need to understand the pattern. In this case, we are given that m4 equals 75.
The superscript number represents the position in the sequence, so m4 means the number at the fourth position in the sequence.
To find the value of m8, we need to identify the pattern that relates the position number to the corresponding value.
In this case, the sequence follows a pattern where each term is multiplied by 2 and then subtracted by 25.
So, to get the value of m4, we can apply the pattern:
m4 = 2 * m3 - 25
Similarly, to find m8, we need to apply the pattern repeatedly:
m5 = 2 * m4 -25
m6 = 2 * m5 -25
m7 = 2 * m6 -25
m8 = 2 * m7 -25
Using the given value of m4 as 75, we can substitute it into the equations and solve step by step.
m4 = 2 * m3 - 25
75 = 2 * m3 - 25
100 = 2 * m3
m3 = 50
m5 = 2 * m4 - 25
m5 = 2 * 75 - 25
m5 = 150 - 25
m5 = 125
m6 = 2 * m5 - 25
m6 = 2 * 125 - 25
m6 = 250 - 25
m6 = 225
m7 = 2 * m6 - 25
m7 = 2 * 225 - 25
m7 = 450 - 25
m7 = 425
m8 = 2 * m7 - 25
m8 = 2 * 425 - 25
m8 = 850 - 25
m8 = 825
Therefore, the value of m8 is 825.
What is the meaning of m 4 ?
Did you mean 4m ? , or m^4, or ....
If 4m = 75, then 8m = 150, not one of the choices.
If m^4 = 75 , then m^8 = (m^4)^2 = 75^2 = 5625 , not one of the choices.
so ..... ??
