How to make an sequences only five
✍• The pattern seems to be that the n-th term is of the form nn. Then the next term, being the fifth term (n = 5) is 55 = 3125. Find the next number in the following sequence: 2, 5, 10, 17, and 26.
✍• There is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.
