Answer 1

Answer:

Answer is 305

Step-by-step explanation:

25 , 49, 89, 145, 217 ?

\ / \ / \ / \ / \ /

24 40 56 72 88

217+88= 305

Answer 2

Answer:

• The series is in the following form:

49−25=−24=4×6

89−49=40=4×10

145−89=56=4×14

217−145=72=4×18

Following the series next number will be

4×22=88

Hence we will add 88 to previous number:

217+88=305

• Hence 305 will be the next number
