WebFirstly, work out the difference. in the terms. This sequence is going up by four each time, so add 4 on to the last term to find the next term in the sequence. 3, 7, 11, 15, 19 , 23 , ... WebThe first thing I have to do is figure out which type of sequence this is: arithmetic or geometric. I quickly see that the differences don't match; for instance, the difference of the second and first term is 2 − 1 = 1, but the difference of the third and second terms is 4 − 2 = 2. So this isn't an arithmetic sequence.

WebAn arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. It is represented by the formula a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common difference, which is obtained by subtracting the previous term ... WebSequences and series are most useful when there is a formula for their terms. For instance, if the formula for the terms a n of a sequence is defined as "a n = 2n + 3", then you can find the value of any term by plugging the value of n into the formula. For instance, a 8 = 2(8) + 3 = 16 + 3 = 19.In words, "a n = 2n + 3" can be read as "the n-th term is given by two-enn plus …
