n+91
(n2 + n)/2 1+2+3+4+5+n= 15+n
8n + (5-n) + 13 = 7n + 18
5 + n = 23 n = 18 18 - 5 = 13 ■
your expression is this... n+5=3+12 n+5=15 n=10
n+5
n+91
n plus 15.n plus 15.n plus 15.n plus 15.
5+n+3 = 8+n
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
(n2 + n)/2 1+2+3+4+5+n= 15+n
No. n is not a factor of n + 5.
2n plus 5 n would be 7n and its impossible to solve the value of n.
8+n
Find the Sum to n terms of the series 5 5+55+555+ +n Terms
5 + n
23+n+5+n=23+5+n+n=28+2nIt depends what n is, once, you find out what n is equal to, plug it in to the equation above in bold.
