Answer 1

Next no in series 700, 1400, 4200 ----

Solution

a=700

b=a*2=700*2=1400

c=b*3=1400*3=4200

d=c*4=4200*4=16800

e=d*5=16800*5=84000

700,1400,4200,16800,84000......

next value can be calculated as previous *(n)

n=2 for second value, n=3 for third value and so on.

Answer 2

16800

It is observed that 700 has been multiplied by 2 =1400
1400 has been multiplied by 3 =4200

therefore, according to series, 4200 should be multiplied 4 = 16800
