Answer 1

$\sf\large\underline{Given:}$

• 3, 4=5
• 4, 5=11
• 5, 6=19
• 6, 7=29

$\sf\large\underline{To\: Find:}$

• $\rm{The\: value\:of\:7,\:8=?}$

$\sf\large\underline{Solution:}$

• At 1st find out the logic to calculate the value of the given expression.we noticed that 1st number should be taken out square and than subtracting from the other number.

$\sf\large\underline{Logic\:used:}$

$\rm\red{\implies 3,\:4=5}$

$\rm{\implies 3^2-4}$

$\rm{\implies 9-4}$

$\rm{\implies 5}$

$\rm\orange{\implies 4,\:5=11}$

$\rm{\implies 4^2-5}$

$\rm{\implies 16-5}$

$\rm{\implies 11}$

$\rm\purple{\implies 5,\:6=19}$

$\rm{\implies 5^2-6}$

$\rm{\implies 25-6}$

$\rm{\implies 19}$

$\rm\green{\implies 6,\:7=29}$

$\rm{\implies 6^2-7}$

$\rm{\implies 36-7}$

$\rm{\implies 29}$

• Similarly calculate 7, 8=?]

$\rm\red{\implies 7,\:8=?}$

$\rm{\implies 7^2-8}$

$\rm{\implies 49-8}$

$\rm{\implies 41}$

$\sf\large{Hence,}$

$\rm{\implies The\: value\:of\:7,\:8=41}$
