?
​

Answer 1

Answer:

There will be 11 dots in figure E.

Explanation:

GIVEN:

Dots on figure A = 1

Dots on figure B = 2

Dots on figure C = 4

Dots on figure D = 7

Dots on figure E = ?

THE PATTERN:

The pattern is as follows:

The no. of dots added in each figure is the adding of the natural numbers 1, 2, 3 and 4 to the previous figure. In figure A there is 1 dot and in the figure B, one more dot is added and so on.

Figure A + 1 = Figure B

Figure B + 2 = Figure C

Figure C + 3 = Figure D

Figure D + 4 = Figure E

No. of dots on Figure D is 7. By adding 4 more dots,

7 + 4 = 11

Therefore there will be 11 dots on Figure E.

Answer 2

Answer:

answer is 11

because:

a+1=2

b+2=4

c+3=7

d+4=11
