If nth term of an AP is an+b then its common difference |
| Answer» We are to find the common difference of an A.P. if its n-th term is given by (an + b).The n-th term of the A.P. is{tex}a_n=an+b.{/tex}Therefore, the (n+1)-th term of the A.P. will be{tex}a_{n+1}=a(n+1)+b.{/tex}We know that the common difference of an A.P. means the difference between two consecutive terms, so{tex} {common difference},~d=a_{n+1}-a_n=(an+a+b)-(an+b)=a.{/tex}Thus, the required common difference is \'a\'. | |

What is the number x ? The LCM of x and 18 is 36 , and HCF of x and 18 is 2 |
|
Answer» LCM*HCF=product of two numbers 36*2=18*x36*2/18=x72/18=x4=xDone HCF * LCM = x * 182 * 36 = 18x36 = 18x ÷2 36 = 9x36÷9 = x4 = x 4 4 \\text {product of the two numbers }=L C M \\times H C FTherefore, the we can substitute the known values in the formula to get the values of "x"{tex}\\begin{array}{l}{x \\times 18=36 \\times 2} \\\\\\\\ {x=\\frac{72}{18}} \\\\\\\\ {x=4}\\end{array}{/tex}Hence the value of unknown number "x" is 4\xa0 X = 4 x= 4 |
