Hey there.
Could someone please help me with 1999 Q5a.
Heres a link to the solutions.
I get to the final line of the solutions but idk why they said that equals the RHS when it clearly doesnt. Any ways, any help would be appreciated

from those solutions it has to equal equation 2 while in the final answer theres an extra (2k-1)

That's the preceding term, the ... in the equation 2 are there in place of it.
