FLM ~ FED
Step by step explanation: from the picture you can see that < L is congruent to < E, as well as that
Pic, top, pit, pot, cot, cop. to, opt, tic, it,
A 1 = 13, d = 3;
S n = n/2 * ( a 1 + a n )
a 7 = a 1 + 6 d = 13 + 3 * 6 = 13 + 18 = 31
S 7 = 7/2 * ( 13 + 31 ) = 7/2 * 44 = 154
Answer:
D ) 154
