it is in the form, 210 = (15)² - 15 and 380 = (15 + 5)² - (15 +5), 182 = 13² + 13 and 342 = 182 + 18

relationship is a: a(a +1)

relationship is a: (7/2 a)

relationship is a : (a + 89)

pattern is (a³ + a)

relationship, a³ : (a + 1)³ + 1

relationship, (a² + 1) : a

relationship, a : (a³ + a)

2 is the first number and difference between 3rd and 2nd number is equal to first number. Hence in option (c), the same follows i.e., difference between 3rd and 2nd Number is 3, which is first number.

The pattern is (3, 3 x 6 = 18, 18 x 2 = 36) then,
(4, 4 x 6 = 24, 24 x 2 = 48) which is option (b).
