Which set of angle measures could be the interior angles of a triangle? a. 15°, 25°, 50° b. 23°, 67°, 90° c. 25°, 58°, 102° d. 38°, 42°, 80°

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
