Answer:
= 2
= k(k+1)
= (k+1)(k+2)
Step-by-step explanation:
We are given the statement,
as 2 + 4 + 6 + . . . + 2n = n(n+1)
That is,
as 2 + 4 + 6 + . . . + 2n = 
So, we have,
= 
= 2
= 
= 2 + 4 + 6 + . . . + 2k = k(k+1)
= = 2 + 4 + 6 + . . . + 2k + 2(k+1) = (k+1)(k+2)
Thus, we get,
= 2
= k(k+1)
= (k+1)(k+2)
Answer:
7
Step-by-step explanation:
also why is 78 there? a factor means in that range
Answer:
2x + 7y + 37
Step-by-step explanation:

= 9 + 2x + 14 + 7y + 14
= 2x + 7y + 37
The correct answer is 58 yes
