Each of these five sequences follows a logical progression.
What is the missing element in each sequence?
Solution to the Problem:
The answers are:(#1) 25 (#2) 4 (#3) 7 (#4) Q (#5) 4
#1 When moving down or to the right, the difference between each successive pair of numbers
increases by 1. Thus, 5 + 2 = 7, 7 + 3 = 10, 10 + 4 = 14, 14 + 5 = 19, and 19 + 6 = 25.
#2 Add 2 adjacent numbers and subtract 6 to get the number below and between them.
#3 Multiply the top by the bottom left corner and then add the bottom right corner to the product.
#4 Each equation is true if each letter is assigned the value of its position in the alphabet.
(A = 1, B = 2, C = 3, etc.)
#5 Starting at either end of either row, add the first and third digits together, then
subtract the second digit to get the number above it.
