Why is output 1-2-4-7-11 instead of 1-2-4-8-16?

Тимур Завьялов arr[i] = arr[i-1]+i; For i=3 arr[3] = arr[2] + 3 => 4 + 3 { as arr[2] is 4 as calculated above } Similar is the case of arr[4] I am curious to know how are you calculating it to be 8 and 16 ?

arr[0] = 1 { initialization } arr[1] = arr[0] + 1 => 1+1 = 2 arr[2] = arr[1] + 2 => 2+2 = 4 arr[3] = arr[2] + 3 => 4+3 = 7 arr[4] = arr[3] + 4 => 7+4 = 11
