Answer 1

Solution-1:-

Let the terms be a,b,c,d

• b=7
• c=35
• d=49

ATQ

$\\ \sf\longmapsto a:b=c:d$

$\\ \sf\longmapsto \dfrac{a}{b}=\dfrac{c}{d}$

$\\ \sf\longmapsto \dfrac{a}{7}=\dfrac{35}{49}$

• Using cross multiplication

$\\ \sf\longmapsto 49a=35\times 7$

$\\ \sf\longmapsto 49a=245$

$\\ \sf\longmapsto a=\dfrac{245}{49}$

$\\ \sf\longmapsto a=5$

First term of proportion is 5.
