Answer 1

Answer:

Series = 20, 25, 30, _____, 140

Formula used:

l = a + (n – 1)d

Here,

l = last term

a = first term

n = number of terms

d = difference between two term (t2 – t1)

Calculation:

d = t2 – t1 = 25 – 20 = 5

Let the number of terms be n

⇒ 140 = 20 + (n – 1)5

⇒ 120 = (n – 1)5

⇒ n = 25

∴ Number of terms = 25

Step-by-step explanation:

4.1) Define modulus function and draw a rough graph of modulus function (2) ii) If f(x)=2x-3 find f(1) and f(0)

A function which always gives a non negative real value irrespective of the input values is called a modulus function.

It is given as

f(x)=∣x∣={

x,x≥0

−x,x<0

Henc the graph of f(x)=∣x∣.

25 × (30 + 20) = 25 × 30 + 25 × 20 __Series = 20, 25, 30, _____, 140

Formula used:

l = a + (n – 1)d

Here,

l = last term

a = first term

n = number of terms

d = difference between two term (t2 – t1)

Calculation:

d = t2 – t1 = 25 – 20 = 5

Let the number of terms be n

⇒ 140 = 20 + (n – 1)5

⇒ 120 = (n – 1)5

⇒ n = 25

∴ Number of terms = 25
