Question

if the first term of an AP is 4 and common difference is -2 what is it's 2nd term?​

Answer 1

       $\underline{\bold{Answer:}}$

       $2$

       $\underline{\bold{Step-by-step-explaination:}}$

       $\text{It is given that: the first term of an AP}(a) = 4$

                                 $\text{the common difference}(d) = -2$

       $\text{We know that the }n^{th}\text{ term of an AP}(a_n)=a+(n-1)d$

$\implies \text{The second term of the AP}(a_2) = 4+(2-1)(-2)$

$\implies \boxed{a_2 = 4+(1)(-2)}$

$\implies \boxed{a_2= 4-2}$

$\implies \boxed{a_2 = 2}$
