Directions: A. Find the missing term in each sequence.
Answer:
31) 10, 15, 20, 25, 30
32) -2, -4, -6, -8, -10
33) 1, 3, 9, 27, 81
34) 7, 12, 22, 37, 57, 82
35) 1, 4, 9, 16, 25 , 36, 49
Solution:
#TO FIND THE NEXT TERM
31) 10, 15, 20, 25, 30
#Added by 5
a1=10
a2=(10+5)=15
a3=(15+5)=20
a4=(20+5)=25
a5=(25+5)=30
32) -2, -4, -6, -8, -10
#Subtracted by -2
a1=-2
a2=(-2-2)=-4
a3=(-4-2)=-6
a4=(-6-2)=-8
a5=(-8-2)=-10
33) 1, 3, 9, 27, 81
#Multiply by 3
a1=1
a2=(1 x 3)=3
a3=(3 x 3)=9
a4=(9 x 3)=27
a5=(27 x 3)=81
34) 7, 12, 22, 37, 57, 82
#Added by multiple of 5 (5,10,15,20,25,...)
a1=7
a2=(7+5)=12
a3=(12+10)=22
a4=(22+15)=37
a5=(37+20)=57
a6=(57+25)=82
35) 1, 4, 9, 16, 25 , 36, 49
#Multiply by with same number to other same number
a1=(1 x 1)=1
a2=(2 x 2)=4
a3=(3 x 3)=9
a4=(4 x 4)=16
a5=(5 x 5)=25
a6=(6 x 6)=36
a7=(7 x 7)=49
