WebApr 11, 2024 · In this paper, a class of octonion-valued neutral-type stochastic recurrent neural networks with D operator is concerned. Except for the time delay, all connection weight functions, activation functions and external inputs of such networks are octonions. Based on the Banach fixed point theorem, the definition of almost periodic stochastic … WebExample: Find the sum of the first 20 terms of the arithmetic series if a 1 = 5 and a 20 = 62. Solution: Here, a 1 = 5 and a 20 = 62 and n = 20. If we have given the first term and the last term, then. S = n/2 [a + a n] Therefore, S = 20/2 [5 + 20] = 10 25 = 250. So, the sum of the first 20 terms of the AP is 250.
