The answer is no solution, if my math is correct.
22.31 because A= BH where B is base length and H is Height. Multiply 5.25 by 4.25 and you get 22.31
Answer: Add like terms
Step-by-step explanation:
For example, you would add 6x and 5x to make 11x, but there other two numbers you would leave alone.
From the recursive rule

it follows that


and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

so that the explicit rule for the n-th term in the sequence is
