Question

Find the general term of the arithmetic sequence whose first term is 4 and common difference is 2

Answer 1

For arithmetic sequence


`a_(n)=a_(1)+d(n-1) a_(1)=4, d=2 a_(n)= 4+2(n-1) a_(n)=4+2n-2=2+2n a_(n) = 2+2n`

Sometimes the answer could be asked in the form

a(n)=4+2(n-1),

Sometimes it could asked in simplified form
a(n)= 2n+2
