Set m contains the values {-12, -7, 4, 11} and set n contains the values {-3,2,8}. what is the greatest possible difference of m^2 - n^2 ?
a. 76
b. 117
c. 140
d. 153

C. 140

Step-by-step explanation:

We want m^2 to be the largest value it can be, so ignoring the sign of m the largest value of |m| is 12

(-12)^2 = 144 which is the largest value of m^2

We want n^2 to be the smallest it can be, so ignoring the sign of n the smallest value of |n| is 2

(2)^2 =4

m^2 -n^2

144-4 = 140

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
