Classify the sequence as arithmetic, geometric, Fibonacci, or none of these and supply the next term. 3, 7, 11, 15, ...
Arithmetic sequence is a series in which each number is different from proceeding one by a constant number (Common diffrerence) | ||||||||||||||||
Series is 3,7,11,15,….. | ||||||||||||||||
Each numbers in the series has a difference of 4 with the preceding number.Hence,it is an arithmetic sequence | ||||||||||||||||
Next term would be 15+4=19 | ||||||||||||||||
Geometric sequence is a series in which each term is found by multiplying the previous on eby a fixed number.Hence,this series is not a geometric sequence. | ||||||||||||||||
Fibonacci sequence is a series in which each number is the sum of the preceding two numbers.Hence,this series is not a fibonacci series. | ||||||||||||||||
