Calculate the first term in the sequence using the formula a = t/[f^(n - 1)], in cases where you are given a single number, t, and its position in the sequence, n, as well as the factor. So if the second term in the sequence (at n = 2) is 6 and f = 2, a = 6/[2...
Learn how to find the terms of a geometric sequence of rational numbers, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.
Example Problem 1: Arithmetic or Geometric Is the sequence1,1,2,3,5,8,13,21,…arithmetic, geometric, or neither? Step 1: See if there is a common difference. Subtract the first term from the second term, and you get zero. a2−a1=1−1=0 ...
Enter the first two terms of a geometric sequence into the calculator below to calculate its sum to infinity. Sum to Infinity Calculator Negative Sum to Infinity The sum to infinity of a geometric series will be negative if the first term of the series is negative. ...
Step 2:Calculate the value of cos(87°).Tip: If you don’t have a scientific calculator, just type “cos 87 degrees” into Google. cos(87°) = 0.05 (to two decimal places). Insert that new piece of information into the formula: ...
