Question

the common difference of an AP n+1, n+2, n+3...is​

Answer 1

AP : n+1, n+2, n+3 .......

Here,

$\text{Common Difference = } \{ \rm{}2^{nd} \: \: term \}- \{1^{st} \: \: term \} \\ \\ \bf \implies( n+ 2) - ( n+ 1) \\ \bf \implies{}\cancel{n } + 2 - \cancel{n }- 1 \\\implies 2 - 1 \\ \sf \implies \red1$

Hence,

• Common Difference of the (given) AP is 1
