The number would be 1 because
3+1= 4x4= 16
Answer:
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1.Find a recursive formula. This example is an arithmetic sequence (the same number, 5, is added to each term to get to the next term).
Yes it is a solution
3(6)-4(5) = -2
18-20 = -2
-2 = -2
so yes (6,5) is a solution.
Use the pythagorean theorem. Solve for the 3rd side which is 3 since a perfect triplet is 3,4,5. 4*2+3*2+1/2(4*3)=20 sq.in. The answer is A.<span />
