Question is:

i) Find the sum of the integers from 29 to 107 inclusive.

ii) Hence find the value of

107

E (4 + 3i)

i = 29

Sorry I don't know how to put in the sigma notation above.

I can follow what to do until it gets to the part in brackets (4 + 3i), I am not sure why it is that value? It doesn't seem to fit in with the rest of the equation when I have calculated it.

Thanks in advance.
