Answer:
The sum is
Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:
We group similar try to get:
We now combine the similar terms to obtain:
Therefore the sum is
N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
