What numbers are both square numbers and triangular numbers?
The only square number that is also a triangular number is 1. This is because square numbers are of the form n^2, while triangular numbers are of the form (n*(n+1))/2. When setting these two equations equal to each other and solving for n, we find that n=1 is the only integer solution. Therefore, 1 is the only number that is both a square number and a triangular number.

How do you find the meadian in a set of numbers?
Order the set from least to greatest. The number in the middle, or the mean of the two numbers in the middle, is the median. That is, if S is the set, then for #S = 2n - 1, Sn is the median, while for #S = 2n, (Sn-1 + Sn)/2 is the median.
What is the difference between an infinite sequence and an infinite series?
A series is a special case of a sequence where the n'th term is the sum of n numbers a1, a2, ..., an. In other words, it is a sequence in the form S1 = a1 S2 = a1 + a2 S3 = a1 + a2 + a3 ... Sn = a1 + a2 + ... + an
What is the arithmetic sequence formula?
the formula is: Sn= n [2(A1)+(n - 1)d] 2 for example the given sequence is when A1 = 4 and n = 10 when d = 2 here is the solution: Sn = 4 [2(4)+(10 - 1)2] 2 Sn= 2 [6+(9)(2) Sn = 2 [6+18] Sn = 2 (24) Sn = 48 see?
