Question

for the AP 3/2,1/2,-1/2,-3/2 ....write the
first term and common-
difference
​

Answer 1

FINAL ANSWER:-

• $a=\frac{3}{2}$

• $d=-1$

GIVEN:-

$AP \:\:\frac{3}{2},\frac{1}{2},\frac{-1}{2},\frac{-3}{2}....$

TO FIND:-

• first term (a1)

• common difference (d)

FORMULAS USED:-

common difference ⇒ $2^{nd}term-1^{st}term$ ⇒ $d=a2-a1$

SOLUTION:-

as first term is the first term of the AP

so

• $a=\frac{3}{2}$

common difference is the difference between each arithmetic progression or term and it is represented with 's'

$d= a2-a1 \\d=\frac{1}{2}-\frac{3}{2} \\d=\frac{1-3}{2} \\d=\frac{-2}{2}$

• $\\d=-1$

hence

first term is $\frac{3}{2}$

common-difference is $-1$
