Our Brief Journey with properties and patterns of Triangular Numbers
Abstract
The triangular numbers are formed by partial sum of the series 1+2+3+4+5+6+7….+n In other words, triangular numbers are those counting numbers that can be written as = 1+2+3+…+ n. So,
T1= 1
T2= 1+2=3
T3= 1+2+3=6
T4= 1+2+3+4=10
T5= 1+2+3+4+5=15
T6= 1+2+3+4+5+6= 21
T7= 1+2+3+4+5+6+7= 28
T8= 1+2+3+4+5+6+7+8= 36
T9=1+2+3+4+5+6+7+8+9=45
T10 =1+2+3+4+5+6+7+8+9+10=55
In this paper some important properties of triangular numbers are studied.
