Select the option in which the numbers are related in the same way as are the numbers of the following set.
{9, 21, 16}
Answer & explanation
Correct answer: option 1
{9, 21, 16}
The logic followed here is :
SQUARE ROOT OF IST NUMBER AND SQUARE ROOT OF IIIRD NUMBER WE GOT BOTH THE VALUE AND ADD IT AND MULTIPLY WITH 3 TO GET THE SECOND NUMBER
AS
{9, 21, 16}
SQUARE ROOT OF 9 = 3
SQUARE ROOT OF 16 = 4
( 4 + 3 ) × 3
= 7 × 3
= 21
SIMILARLY IN OPTION 1
{36, 42, 64}
SQUARE ROOT OF 36 = 6
SQUARE ROOT OF 64 = 8
( 6 + 8 ) × 3
= 14 × 3
= 42
