Answer:

a₅ = 2701.125

Step-by-step explanation:

Multiply each term by 3.5 , that is

a₁ = 18

a₂ = 3.5 × 18 = 63

a₃ = 3.5 × 63 = 220.5

a₄ = 3.5 × 220.5 = 771.75

a₅ = 3.5 × 771.75 = 2701.125

Slove the following:

Aleksandr [31]

Answer:

let required no be x

$\frac{1}{7} = \frac{x}{42}$

by doing crisscrossed multiplication

$42 \times 1 = 7 \times x$

42=7x

dividing both side by 7

$\frac{42}{7} = 7x \div 7$

6=x

therefore x=6

therefore value of remaining no.is 6
