Devise an algorithm that finds the first term of a sequence of positive integers that is less than the immediately preceding term of the sequence.

Solution:Step 1:We are required to compose an algorithm according to the question. We initially investigate what an algorithm is and the essential steps to be followed in composing an algorithm.Step 2:Definition of the algorithm: An algorithm is an all around characterized system that enables a PC to take care of an issue. Another approach to describing an algorithm is an arrangement of unambiguous directions. The utilization of the expression "unambiguous" shows that there is no space for subjective understanding. Each time you request that your PC do a similar algorithm, it will do it in the very same way with precisely the same.
