#Arithmetic and geometric sequences formula sheet series

(Think of subtraction as adding a negative number and these can all be written as addition patterns.) 9) Go back and circle the problem numbers in the above sequences (1-8) which represent Arithmetic sequences. Formulas for the nth terms of arithmetic and geometric sequences For an arithmetic sequence, a formula for thenth term of the sequence is a n 5 a 1 n 2 1d. Sequences involving repeated addition or subtraction are known as Arithmetic. a) a = 1 r = 3 tn = 1(3)n 1 b) a = 12 r = c) a = 9 r = - 3 tn = 9(-3)n 1 5. For an arithmetic sequence we get thenth term by adding d to the rst term n 2 1 times for a geometric sequence, we multiply the rst term byr, n 2 1 times. Hint: you will need to find theformula for tn first!a)2, 5, 8. A really great activity for allowing students to understand the concept of Arithmetic and Geometric Sequences.

your formula from question 4c) to find the values of the t4 and the number of terms in the following Arithmetic Sequences. b) The nth term of the arithmetic sequence.

Geometric Sequence and Series A Sequence and Series Formula Sheet PDF: Download List. the following Arithmetic Sequences, find a and d and state the formula for the general t forget to simplify!Ģ A) - 10, - 4, 2, 8, 14.

If they are Geometric, state )6, 12, 18, 24. 486) Outline: Sequences Difference between arithmetic and geometric sequences Arithmetic Sequences Geometric Sequences. 1 Tn = tn = Date: _Arithmetic and Geometric Sequences WorksheetArithmetic sequence - is a sequence of termsthat have a common _ Term: Geometric sequence - is a sequence of termsthat have a common _ the following Sequences Arithmetic, Geometric, or neither? If they are Arithmetic, state thevalue of d.
