Question

if nth term of an AP an=24-3n then find second term​

Answer 1

$\red{ \mathsf{ \huge \fbox{Solution : }}}$

Given ,

nth term or general formula of an AP is 24 - 3n

Put n = 2 in nth term of an AP , we get

$\sf \hookrightarrow 24 - 3(2) \\ \\ \sf \hookrightarrow</p><p>24 - 6 \\ \\ \sf \hookrightarrow</p><p>18$

Hence , the second term of an AP is 18
