What is the value of m2-2mn+n2 for m=-2 and n=4

 The required value is 36.

Step-by-step explanation:  We are to find the value of the following expression for m = -2 and n = 4 :

Substituting the values m = -2 and n = 4 in the given expression, we get

Thus, the required value is 36.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

middle maybe?
