To solve the third term of 10-n², substitute the number 3 for n. 10-n² =10-3² =10-9 =1 The third term of 10-n² is 1.
To find one third of any number, divide the number by 3.Example: 9 ÷ 3 = 3
n means any number in the sequence.Let's take for example the sequence; x=0,2,4,6,8,10,12,14when x=4, then n=3, because 4 is the third number in the sequence
n= first number n+1= second number n+2= third number n+3= fourth number n+4= fifth number So, this equation makes sense, and then you solve it: 5n+5=900 -5 -5 5n=855 /5 /5 n=171 So the answer is 171, 172, 173, 174, and 175.
That is basically a cubed root. If you know the cubes (1, 8, 27, 64, 125, ...) then you can estimate the value of n(1/3) where n = any number.
