To determine the sum of the arithmetic series, simply remember that i is the pattern that you are going by which is 1,2,3.
The top value on the sigma sign tells you the final value that you must go to.
So use the equation to go from 1 to 18. So it would be 2(1) + 9 + 2(2) + 9 etc.
What is a magic number puzzel
To answer this exponent we will multiply the base by the power. Lets do it:-
10 = base
2 = power
10² = 10 × 10 = 100
10² = 100
CHECK OUR WORK:-
√100 = 10
We were RIGHT!!!
So, 10² = 100.
Hope i helped ya!! :)

Step-by-step explanation:
body = x
tail = 7x
x + 7x = 48
