Question

Help Please!
find the 2nd term of an arithmetic sequence if t1=0 amd t5=16?

Answer 1

Well arithmetic formula is
\[T_n=a_1+(n-1)d\]
--------------------------
\[T_1=a_1+(1-1)d=0 \]
getting
\(a_1=0\)
--------------------------
\[T_5=0+(5-1)d=16\]
solve for d then apply arithmetic formula again for t2

Answer 2

4?

Answer 3

yes now use
\[T_n=a_1+(n-1)d\]
for n=2
