Find sum of series 1+2+8+26+80+…….+n

we can not define 1+2+8+26+80+.......... series in a simple manner to write  program. But..... 2,8,26,80,242.................can be define as below The way to discover the next term is multiply the next number by 2 and then add it on. i.e. the next number of 2 is 3 so, 3*2=6+2=8 9*2=18+8=26 27*2=54+26=80........ and so on             OR … Continue reading Find sum of series 1+2+8+26+80+…….+n
