Question

10th term of AP 2,7,12 ____ is

Answer 1

$\huge\boxed{\underline{\mathfrak{\red{   answer}  }    }  }$

${  AP \: is\:2,7,12 .....................         }$

${  1st\:term=a=2         }$

${   2nd\:term=7        }$

$\implies{  difference=d=7-2=5         }$

${    10th\: terms\: of \:AP       }$

$\implies{\red{ (a+(n-1)×d       }   }$

$\implies{   2+(10-1)×5        }$

$\implies{ 2+(9×5)          }$

$\implies{ 2+45          }$

$\implies\boxed{\purple{    47   }    }$

Answer 2

Step-by-step explanation:

1stterm=a=2        

 2ndterm=7              

⟹  difference=d=7−2=5        

⟹ (a+(n−1)×d         

⟹   2+(10−1)×5       

⟹ 2+(9×5)         

⟹ 2+45        

⟹    47
