n alternating series is a —select— whose terms are —select— . (b) under what conditions does an alternating series converge?

An alternating series is a whose terms are alternately positive and negative.

The alternating series ,

∑_(n=1)^∞ a_n=∑_(n=1)^∞ (-1)^(n-1) b_n

where bn = lanl, converges if 0<b_(n+1)≤b_n for all n

lim_(n→∞) b_n=0

Subtraction:

Subtraction serves as a representation for the act of removing items from a collection. The negative symbol stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above illustration) are then transported to a basket, the stack will now contain five oranges rather than nine.

Therefore, the difference between 9 and 4 is 5, which equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter “-” represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.
