We have a statement
26 more than twice a number
Let the number is n, then
The statement will be 26 more than twice n
Twice means multiply by 2, then
The statement will be 26 more than 2 x n
More than means add, then
The statement will be 26 + 2 x n
Then the algebraic expression is

The answer is 26 + 2n OR 2n + 26
