math question arthematic mean please help me

<p>4,11,18 /in the sequence above,the first term is 4 and each term after the first is 7 more then the previous term. what is the 12th term of the sequence? A(77) B(11)C(84)(D(86)E(92) its b ik but i needed to make 4 plus 7 11 times is there and esier way to do this cause somethimes they can tell u in the term of 121 or something</p>

<p>Using arithmetic progression , it will always follow the formula "nth term= a + (n-1)d " . where a is the first term , n is the number of the term and d is the difference. So the 12th term would be 4 + (12-11)(7) so just type that into your calculator with the brackets and all . Hope this helps !!</p>

<p>what is the 11?</p>

<p>sorry i meant (12-1) *** Btw the ans is 81 and not 11 ( which is what you typed in the original post ) right ???</p>

<p>Or you could use simple logic. What is the SECOND term in the sequence? That is 11.
Would adding ten numbers not yield the 12th term? And what is 10 x 7?
In so many words, all you need to do it add 70 to the SECOND term for the answer that is … 81.</p>
