Given the Arithmetic series A1+A2+A3+A4
natali 33 [55]

Answer:

S _{19}  = 760

Step-by-step explanation:

a1 = 13 \\ a2 = 16 \\ d = a2 - a1 = 16 - 13 = 3 \\ d = 3 \\ a _{n}  =  l = 67 \\

now,

a _{n} = a + (n - 1) \times d \\ 67 = 13 + (n - 1) \times 3 \\ 67 = 13 + 3n - 3 \\ 67 - 13  + 3 = 3n \\ 57 = 3n \\ 3n = 57 \\  \\ n =  \frac{57}{3}  \\  \\ n = 19

now the sum of the numbers

S _{n} =  \frac{n}{2} (a + l) \\  \\ S _{19}  =  \frac{19}{2}   (13 + 67) \\  \\ S _{19}  =  \frac{19}{2} (80) \\  \\ S _{19}  =  \frac{19}{2}  \times 80 \\  \\ S _{19}  = 19 \times 40 \\ S _{19}  = 760
