Question

(i) Find three consecutive numbers whose sum is 108
(ii) Find three consecutive odd numbers whose sum is 93

Answer 1

Let the 3 commutative no be $a-1,a,a+1$

So, $a-1+a+a+1=108$

$3a=108\Rightarrow a=36$

Numbers are $35,36,37$

Let the 3 commutative odd no. be $a-2,a,a+2$

So, $a-2+a+a-2=93$

$\Rightarrow 3a=93\Rightarrow a=31$

Numbers are $29,31,33$
