Formulas for sequence and series
WebSo this is an arithmetic sequence with step d=5 and first term a_ {1} = 3 . Our formula above gives a_ {n} = a_ {1} + (n-1)d = 3 + (n-1)5 . For a_ {101} we plug in n=101 into this formula to obtain a_ {101} = 3 + (100)5 = 503 . Part 2: Geometric Sequences Consider the sequence 2, 4, 8, 16, 32, 64, \ldots. WebUsing the formula for the n th term of a geometric sequence and series: a n = ar (n-1) Putting the known values in the formula: a 5 = 1 (1/2) (5-1) a 5 = (1/2) (4) a 5 = 1/16 Answer: The next term of the sequence is 1/16. …

WebSince arithmetic and geometric sequences are so nice and regular, they have formulas. For arithmetic sequences, the common difference is d, and the first term a1 is often referred to simply as "a". Since we get the next term by adding the common difference, the value of a2 is just: a2 = a + d. Continuing, the third term is: a3 = ( a + d) + d ...
