Question

3. Look at this series: 22, 21, 23, 22, 24, 23, ________________What number should come

next?​

Answer 1

Answer:25

EXPLANATION:

In this series we observe that THE NUMBERS ARE SUBTRACTING FROM 1 AND ADDING WITH 2..

Rule = (first number - 1) (second number + 2) (third number - 1) (fourth number + 2)...

we observe

(22-1=21),(21+2=23),(23-1=22),(22+2=24),(24-1=23),(23+2=25)....

SO THE ANSWER IS 25
