If \(p,18,25,32,\ldots\) is an arithmetic progression, what is the value of (p)?

If (5,11,n,23) are consecutive terms of an arithmetic progression, what is (n)?
C. (17)

Which option has (a=14) and (d=4)?
B. \(14,18,22,26,\ldots\)
\(14,18,22,26,\ldots\) में पहला पद (14) और अंतर (4) है। (a) और (d) दोनों शर्तें साथ में जांचें। / In \(14,18,22,26,\ldots\), the first term is (14) and the difference is (4). Check both (a) and (d) together.

What is the difference between the third and fourth terms of \(75,69,63,57,\ldots\)?
B. (-6)
तीसरा पद (63) और चौथा (57) है इसलिए अंतर (57-63=-6) है। अंतर निकालते समय अगला पद घटा पिछला पद करें। / The third term is (63) and the fourth is (57), so the difference is (57-63=-6). While finding difference subtract the previous term from the next term.

If (a=3.5) and (d=2.5), what is the second term?
C. (6.0)
दूसरा पद (a+d=3.5+2.5=6.0) है। दशमलव जोड़ते समय अंकों को सही स्थान पर रखें। / The second term is (a+d=3.5+2.5=6.0). While adding decimals keep digits in proper places.

B. (9)
((t+9)-t=9) है इसलिए अंतर (9) है। समान जोड़ी गई संख्या ही (d) होती है। / ((t+9)-t=9), so the difference is (9). The equally added number is (d).

In an arithmetic progression, the first term is (22) and the second term is (16). What is (d)?
B. (-6)
(d=16-22=-6) है। दूसरा पद छोटा हो तो (d) ऋणात्मक होता है। / (d=16-22=-6). If the second term is smaller, (d) is negative.

In an arithmetic progression, (d=9) and the second term is (20). What is the first term?
B. (11)
पहला पद (20-9=11) है। दूसरे पद से (d) घटाकर पहला पद मिलता है। / The first term is (20-9=11). Subtract (d) from the second term to get the first term.

B. (x=10,y=15)
(5) से (20) तक तीन समान अंतर हैं इसलिए \(d=\frac{20-5}{3}=5\), अतः (x=10) और (y=15)। दो पदों के बीच समान अंतर बांटकर खाली पद निकालें। / There are three equal gaps from (5) to (20), so \(d=\frac{20-5}{3}=5\), hence (x=10) and (y=15).
