Question

find the next term in the series 5,10,30,70...................

Answer 1

Answer:

Step-by-step explanation:

first term (a)=5

second term =10

common difference (d)= second term - first term =

10 -5=5

d=5

Answer 2

Answer: Next term will be 110.

Step-by-step explanation:

Since we have given that

$5,10,30,70,......$

First term = 5

Second term = 10

Difference between first and second is given by

$10-5\\=5$

Third term = 30

Difference between second and third is given by

$30-10=20$

Fourth term = 70

Difference between third and fourth is given by

$70-30=40$

Relation between differences is

$5,20,40\\\\i.e.\\\\5\times 4=20\\\\20\times 2=40\\\\40\times 1=40$

Hence, next term will be 70+40=110.
