Find first 4 terms and the 10th term of each question. 1)n2+3 2) 2n2

1) 4, 7, 12 and 19

Tenth term = 103

2) 2, 8, 18, 32

Tenth term =200

Step-by-step explanation:

Given the nth term of the sequence

1) f(n)= n²+3

When n = 1

f(1) = 1²+3

f(1) = 4

When n = 2

f(2) = 2²+3

f(2) =4+3

f(2) = 7

When n = 3

f(3) = 3²+3

f(3) = 9+3

f(3)=12

When n =4

f(4) = 4²+3

f(4) = 16+3

f(4) = 19

The first four terms are 4, 7, 12 and 19

f(10)= 10²+3

f(10) = 103

Tenth term is 103

2) f(n) = 2n²

When n = 1

f(1) = 2(1)²

f(1) = 2

When n = 2

f(2) = 2(2)²

f(2) = 2(4)

f(2) = 8

When n= 3

f(3)= 2(3)²

f(3) = 2(9)

f(3) = 18

When n= 4

f(4) = 2(4)²

f(4) = 2(16)

f(4) =32

The first four terms are 2, 8, 18, 32

f(10) = 2(10)²

f(10) =2(100)

f(20) = 200

The tenth term is 200

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
