Arithmetic Sequence - GCSE Maths - Steps, Examples & Worksheet

WebUsing the explicit rule of an arithmetic sequence, we have the following: a n = a 1 + ( n − 1) d 77 = 7 + ( n − 1) 7 11 = 1 + ( n − 1) n = 11 Now that we have a 1 = 7, a n = 77, and n = 11, we can use the sum formula to find the value of the arithmetic series. S n = n ( a 1 + a n) 2 = 11 ( 7 + 77) 2 = 11 ( 84) 2 = 11 ( 42) = 462 WebImagine the sequence of whole numbers from 1 to 10 written out. Then imagine the same sequence written in reverse order just below the first. When you add the vertical pairs of corresponding terms, you will get the same result each time, which in this example is 11 (1+10=11, 2+9=11, 3+8=11 ...). greenville south carolina school shooting https://davidlarmstrong.com

WebWhen the sequence is given as "a (j) = a (1) + dj" (i.e. the common difference is added to the first term) it translates directly to "y = mx + b" with y = 0*x + b when x=0). Similarly, the 1st term of a geometric sequence is in general independent of the common ratio. WebAny term of the quadratic sequence can be found by substituting for \ (n\), like before.
