WebSeries Questions with Solutions 1. Write the arithmetic series for the given sequence 5, 10, 15, 20, 25, ….., xn. Solution: Given sequence: 5, 10, 15, 20, 25, ……, x n. Therefore, the arithmetic series for the given sequence is 5 + 10 + 15 + 20 + 25 + …… + x n. 2. Write the formula for arithmetic and geometric series. Solution: WebThe common series tests for real series actually establish absolute convergence, so the ratio test, for example, carries over. But some complex series converge conditionally, just like real series. So this is not a necessary condition. lampada super led h4 8000k
