Look at these1x4(2 x3)-22 x5 (3 x4)-24×7 = (5×6)-2Write the next two lines in this pattemIf we take four consecutive natural numbers, what is the relationbetween the products of the first and the last, and the product ofthe middle two? dWrite this as a general principle in algebra and explain it.

Answer»

> 5×8=(6×7)-26×9=(7×8)-2>4 consecutive natural number will be n,n+1,n+2,n+3then product of first and last term=n(n+3)=n²+3nproduct of middle terms=(n+1)(n+2)=(n²+3n)+2product of middle terms=(product of first and last)+2
