Question

When the fifth term of an arithmetic sequence whose  common difference is D=six and whose first term is a1 =four

Answer 1

28 is the answer

Explanation:

in an arithmetic sequence nth term An is given by the equation

`an \: = a1 + (n - 1) * d`

where A1 is first term and d is common difference. thus from the question we have

`a5 = 4 + ((5 - 1) * 6) \\ = 4 + (4 * 6) \\ = 4 + 24 \\ = 28`
