Question

4A, 7B,13D,25G,_____​

Answer 1

4+3x2⁰=7

7+3x2¹=13

13+3x2²=25

Next= 25+3x2³= 25+24= 49

A=1

B=2=1+1

D=4=2+2

G=7=4+3

Next=7+4=11=K

Total next= 49K

Answer 2

The missing term(?) is "49K".

Step-by-step explanation:

The given series,

4A, 7B, 13D,25G,_____​

The pattern follow:

In numbers,

+ 3, + 6, + 12, + 24, .....

In letters,

+ 1, + 2, + 3, + 4, + .....

7 = 4 + 3 = 7

13 = 7 + 6 = 13

25 = 13 + 12 = 25

? = 25 + 24 = 49

Also,

B = A + 1 = B

D = B + 2 = D

G = D + 3 = G

? = G + 4 = K

Hence, the missing term(?) is "49K".
