The nth term of sequence is 5n+10. The sum of consecutive terms is 145. Find the values of these terms.
-----
nth term:: 5n+10
n+1 st term:: 5(n+1)+10 = 5n + 15
------
Equation::
5n+10 + 5n+15 = 145
------
10n + 25 = 145
10n = 120
n = 12
------
nth term:: 5n+10 = 5*12+10 = 70
n+1 st term:: 5n+15 = 5*12+15 = 75
