Nth term of 1, 4, 9, 16

= n²

Step-by-step explanation:

Note that this is a sequence of square numbers, that is

1 = 1² , 4 = 2² , 9 = 3² , 16 = 4² , thus n th term is

= n²

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
