Question

Find the range of a, where z = w. Details below.

Answer 1

\[z = \sum_{n=a}^{a+1}n\]
\[w=\sum_{m=z}^{z+1}m\]

Function w uses z, which itself uses a, where a = any real number

Answer 2

Big hint.
\[
z=a+a+1\\
w=z+z+1
\]

Answer 3

You equate them then.

Answer 4

z = a+a+1
w=(a+a+1)+(a+a+1)+1

Answer 5

2a+1 = (2a+1)+(2a+1)
2a+1 = 4a+2
------------
2a = 4a+1|
a = (4a+1)/2

Answer 6

4a-2a=?

Answer 7

Oops, forgot the +1
