Question

2=3+3=8+4=15+5=24+TAR+7=??

Answer 1

The missing number is 48.

Explanation:

We have,

2 = 3, 3 = 8, 4 = 15, 5 = 24,

Find the value of 7 = ?

The pattern follow,

x^{2} -1.x2−1.

3 = 2^{2} -1 = 4 - 1 = 33=22−1=4−1=3

8 = 3^{2} -1 = 9 - 1 = 88=32−1=9−1=8

15 = 4^{2} -1 = 16 - 1 = 1515=42−1=16−1=15

24 = 5^{2} -1 = 25 - 1 = 2424=52−1=25−1=24

Similarly,

?  = 7^{2} -1 = 49 - 1 = 48? =72−1=49−1=48

Hence, the missing number is equal to "48".
