2, 7, 14, 23, ?, 47
A. 31

B. 28

C. 34

D. 38

Answer 1

check the difference forms an arithmetic sequence..
7-2=5
14-7=7
23-14=9
?-23 =11 so the reqd number is 34

Answer 2

It goes +5, +7, +9, so the next is +11. So the answer is C, 34.

Here the answer would be 60? Right?

Answer 4

6 - 4 = 2
12/6 = 2
14 - 12 = 2
28/14 = 2

So, yes, 30 x 2 = 60, which is the right answer.

Answer 5

I need some help with some coding-decoding questions..
Can you explain me what I need to do?

1) If FRIEND is coded as HUMJTK, how can CANDLE be written in that code?

A. DEQJQM

B. DCQHQK

C. EDRIRL

D. ESJFME

Answer 6

Okay, here is how it works. Writing out the alphabet, ABCDEFGHIJKLMNOPQRSTUVWXYZ, and then noting how each letter in FRIEND changes to HUMJTK: F +2, R +3, I +4, E +5, N + 6, and D +7. So then CANDLE would be C +2, A +3, N +4, D +5, L +6, and E +7.
