Given : Sanjay's present age is 'y' years

a) Sanjay's age 7 years from now

Present age of Sanjay is 'y' years, After 7 years Sanjay's age will be y + 7

So, the algebraic expression is y + 7

b) Sanjay's brother's age is 4 years less than Sanjay's present age

Present age of Sanjay is 'y' years and Sanjay's brother is 4 years less than Sanjay's present age. It means Sanjay's brother present age is y - 4

So, the algebraic expression is y - 4

c) Sanjay's mother's age is 3 times that of Sanjay's present age

Present age of Sanjay is 'y' years and Sanjay's mother is 3 times that of Sanjay's present age. It means Sanjay's mother present age is 3y

So, the algebraic expression is 3y

d) Sanjay's grandfather's age is 30 years more than Sanjay's mother's age.

We found that Sanjay's mother present age is 3y and Sanjay's grandfather's age is 30 years more than Sanjay's mother's age. It means Sanjay's grandfather present age is 3y + 30

So, the algebraic expression is 3y + 30

e) Sanjay's father's age is 8 years more than 6 times Sanjay's age

Present age of Sanjay is 'y' years and Sanjay's father is 8 years more than 6 times of Sanjay's present age. It means Sanjay's father present age is 6y + 8

So, the algebraic expression is 6y + 8

Answer from: Quest

if a = 1, and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

Square root of a^6b times, cube root of a^2b^7

Answer from: Quest

$a_1 = 1$ , and

$a_{n+1} = a_n + (n + 1)$ for $n \ge 1$

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote $a_1 = 1$ , $a_2 = 3$ , $a_3 = 6$ , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from $a_1 = 1$ , to get to $a_2 = 3$ , we add $2(=1+1)$

from $a_2 = 3$ , to get to $a_3 = 6$ , we add $3 (=2+1)$

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

$a_1 = 1$ , and $a_{n+1} = a_n +(n + 1)$ for $n \ge 1$
