the sequence 29, 31, 33, 35, 37.... 49 has 11 terms. Evaluate the related series..
my teacher said its 429 don't see how she got it

  • algebra -

    I believe you just add 29+31+33+35+37+39+41+43+45+47+49 which are 11 terms =429

  • algebra -

    sum = #of terms(first + last)/2
    = 11(29+49)/2
    = 429
