If $\frac{3 + 5 + 7 + . . . . . . n t e r m s}{5 + 8 + 11 + . . . . . . . . . + 10 t e r m s}$ = 7, the value of n is:

\frac{3 + 5 + 7 + . . . . . . + n (t e r m s)}{5 + 8 + 11 + . . . . . + 10 (t e r m s)} = 7

n

\frac{2 + 5 + 8 + . . . . . n t e r m s}{7 + 11 + 15 + . . . . . . . . n t e r m s} = \frac{23}{35}

\frac{2 + 5 + 8 + . . . . n t e r m s}{7 + 11 + 15 + . . . . . n t e r m s} = \frac{23}{35}
