This i<span>s a Changing Difference Sequences:
Given: </span> 11 20 35 56 <span>83
</span>1st difference : 9 15 21 <span>27
</span>2nd difference: 6 6 <span>6
</span>
Formula : <span>nth term = a + (n - 1)d + ½(n - 1)(n - 2)c
</span>a <span>= first term = 11
</span>c = <span>second difference = 6
</span>d <span>= difference between the first and the term
So </span><span>we substitute all these known values into the formula:
n</span><span>th term = 11 + (n - 1)(9) + 1/2(n - 1)(n - 2)(6)
nth term </span><span>= 11 + 9n - 9 + 3(n - 1)(n - 2)
</span>nth term = <span>11 + 9n - 9 + 3(n² - 3n + 2)</span>
nth term = 11 + 9n - 9 +3n² - 9n + 6
nth term = <span>3n² + 8
</span>
Answer: 3n² + 8
