If each letter of the alphabet is worth two more than its preceding letter, where A is the first number and equals 1, B is the s
andrey2020 [161]

Answer:

<h2>The total value of all the letters in the alphabet is 676.</h2>

Step-by-step explanation:

The problem is about an arithmetic sequence where the difference is 2, the first term is 1 and we know that the alphabet has 26 letters.

To find the total sum of all values, we have to use the following formula

S_{n}=\frac{n}{2}(2a_{1}+(n-1)d )

Where n=26, a_{1}=1 and d=2. Replacing values, we have

S_{26}=\frac{26}{2}(2(1)+(26-1)2) =13(2+50)=13(52)=676

Therefore, the total value of all the letters in the alphabet is 676.
