Question

Find the missing term in the series given below.

74, 75, 78, ?, 114, 195

Answer 1

The missing number is equal to 87.

• The number series is given below.
• To find the missing number, let's do some practice.
• First, find the difference.
• After that multiply the term to find the missing numbers i.e. x and y.

Solution:

• 74, 75, 78, ?, 114, 195
• Difference: 1, 3, x, y, 81
• => 1 x 3, 3 x 3, 9 x 3, 27 x 3
• x = 78 + 9 = > x = 87
• y = 87 + 27 => y = 114
• So, the missing number is equal to 87.
