The next number in the series 20, 23, 28, 14, 17, 22, 11, is:

Answer 1

15 is the answer of your question

Answer 2

$Given \: series \: 20,23,28,14,17,22,11 :$

/* Observing the series , we conclude that */

$First \: term = 20$

$Second \: term = 20 + \pink {3} = 23$

$Third \: term = 23 + \pink {5} = 28$

$Fouth \: term = 28 + \red {\frac{-28}{2}} = 14$

$Fifth \: term = 14+ \pink {3} = 17$

$Sixth \: term = 17 + \pink {5} = 22$

$Seventh \: term = 22 + \red {\frac{-22}{2}} = 11$

$Next \: term = 11 + \pink {3} = 14$

Therefore.,

$\red { Next \:term } \green {= 14}$
